Serpentegena writes "A joint research project by scientists at Harvard University and BBn Technologies may have spawned a new breed of Metronet. The wireless network, code-named CitySense, which will consist of 100 streetlamp-mounted nodes by 2011, will draw power off the Cambridge, Mass. public grid and be used at first for weather and pollution monitoring. The intention is to also allow 'academic researchers worldwide [...] to submit their own research programs to run on the network.' Sounds remarkably similar to the beginning of the ARPANET, except the network hosts will be running Linux."
