The undeadly editors have tracked down the author, Sylvestre Gallon, a first-time OpenBSD contributor, and asked him about his experience of getting libfuse into OpenBSD. Long story short: it involves some vfs grokking, improved fusebufs and a BSD rewrite of the GPL libfuse. Although to actually enjoy the feature, you'd still have to subject yourself to GPLv2 in the ports tree: sysutils/sshfs-fuse and ntfs-3g ports are available.
