Smart Dust 109
kris writes "The german Telepolis magazine from Heise put up a small article about Kris Pister and Randy Katz creating small laser-driven wireless communicating swarm-computing nano-devices called MEMS. This is right out of a Neal Stevenson novel, The Diamond Age. The article is in english language.

Smart Dust in Vernor Vinge novel (Score:1)
Vernor Vinge also also has been thinking about smart dust. Check out his latest novel "A Deepness in the Sky". About midway through, he introduces 'locators', microscopic microwave-powered sensors/computer systems. There are some interesting shenanigans the main characters get into with them. The novel is also good because of an interesting alien race.
The civilizations in the novel don't develop full nanotech nor smart AI because they're stuck in the "Slow Zone" which It should be noted, that Vinge invented to keep the action at a human-comprehensible level. Mr. Vinge was one of the first SF writers to realize that with AI and IA (intelligence amplification) that our civilization will quickly develop individuals who are many orders of magnitude smarter than we are now (literally Marvin the Android's "brain the size of a planet" stuff).
This creates a problem for him as a SF writer, because a realistic, hard SF novel that takes place 100 years from now would be incomprehensible to us now, and of course impossible for him to write. So he's created a significant crutch in the "Slow Zone" to prevent people from getting too smart, and nanotech from getting too good.
An earlier novel "A Fire Upon the Deep" gives us a peek at the "Beyond" where FTL and limited nanotech is possible, and the "Transcend" where super-AIs and unlimited nanotech is possible. A very good read, and I highly recommend it to anyone interested in the future.

Bioweapons (Score:1)
Anthrax works TOO well. That's why there's a push for "something better". You don't want your bioweapons to turn on you. Ideally, a bioweapon should infect only the enemy. Easily transmissible diseases are thus a rather poor choice, as they might well end up infecting ones own people. An effective bioweapon is also fast-acting and short-lived. You don't want the enemy to be able to fight for months or years before getting too sick, nor do you want to keep on slaughtering them after they surrender.
A disease agent transmissible only by injection seems an ideal biological payload for these "nanites". They'd have to have enough processing power to identify friend or foe, and then deploy the payload only in foes.
Better than a biological agent, though, would be some sort of concentrated toxin. No replication means fewer problems with containment. Then when the war is over, nanites with antitoxin payloads could be deployed.

Some years ago I used to read sci.nanotech and a couple of guys there had an idea they called "utility fog". It started out as a design for a really effective nanotech seat-belt and then developed other applications to the point where it was practially the only machine you would ever need.
The idea is to build really small general-purpose nanobots, each (say) 5 um on a side, but with 4 reasonably strong arms capable of reaching out about 50um. They can fly easily by flapping the arms suitably, so you fill your surroundings with a grid of these things spaces 100um apart (replacing 0.01% of the air). Normally they have their arms mostly folded, and are a hardly noticeable dust in the air, but when needed, they can join arms and form a diamond-like grid, which would be very strong. Used as a seatbelt, they would grab each other, or your body (including the insides of your lungs) and lock everything solid, while crumpling from the outside to absorb incoming impacts. They might even be able to double as an ejector seat to throw you clear (and then turn into a parachute!).
If you could do this, the fog would have an incredible number of other applications -- tent, umbrella, clothing, personal digital assistant, furniture, diving suit and air-hose....
Speculating about this struff is great fun, but I never saw the thermodynamic problems addressed -- how do you get power in and waste heat out? Also the idea of someone hacking into your personal fog cloud is frankly terrifying.

If you can find some method of keying the nanites so that they only release the payload to their intended target(s) then you are onto a winner, but you would have to be pretty certain that they would a)Reach the intended target and either b)Destroy the payload or c)Hold onto the payload indefinately if they don't find their target.

Not nanotech, still worth doing (Score:1)
There is an interesting effort [mit.edu] at MIT, and similar efforts elsewhere, to develop the flavor of software engineering that will be appropriate for these kinds of things. It stretches the imagination a bit: each dust mote will have a pretty small amount of memory available, but the whole cloud of them will have a large amount of memory taken together. So it's not inconceivable that a large cloud might run a large program, where each mote held only a small amount of the entire executable.
If you draw a space-time diagram, and imagine how information passes around as a program is running, you can quickly convince yourself that this would be an excellent architecture for large-scale simulations, like molecular modeling, weather prediction, economic modeling, finite element analysis, and so forth.
The great hope for making such computing clouds economical is fault tolerance. The programming model requires you to assume from the outset that you won't know the exact location or orientation of the neighboring motes with which you are communicating. It is a very small step to say that some percentage of the motes might not work (say, 10 or 15 percent). This means you can be very sloppy about some QA issues that, done well as is required with current systems, are very expensive. So 85% reliable dust motes may end up giving you many more MIPS for your computing dollar.
It ain't real nanotech, but it's worth doing. It will put computer science where it needs to be when real nanotech arrives.

I don't think so -- it would be too hard to control where they go. Either they would have to rely on wind (human-provided or natural) to move around, or some other delivery mechanism, to get to their desired targets. No matter how small they are, they can't break the laws of physics, which means that they've got to expend energy to move, and this would seriously affect their range of deployment. In most cases, it would prove to be more effecient to choose some other means of delivery. I'm not saying that some bright minds won't come up with new propulsion methods (magnetic, laser, etc), but at least for now I don't think we have to worry about this aspect of the devices.

What these buggers need is something akin to "locus" communication. That is, one particular mote should communicate only with the few within a very small range, and receive communications from them. Swarms of locusts, or flights of birds work this way, for instance. A bird, for instance, patterns its flight after the birds nearer to him, and they are all connected in a single pattern that seems perfectly synchronised.
Then, the swarm of motes can communicate as a single entity back to the central or whatever it may be, and this works regardless of how many mites are destroyed by accidental sneezing or a sudden itch.
