As for the blind leading the blind, how about a teleconferencing link to Boston or Silicon Valley? A company I worked for tried having a couple of webcams/projectors in a meeting room during a Friday social hour to try and link the Connecticut and Houston offices. It only went so far. But maybe if you had an entire wall of an old school "terminal room" style workroom, this could work. Have 3 connected projector/webcam sets linked on a pair of dedicated machines, with software that could quickly and rapidly change functions of the two side screens. (Add some Wiimote hackery for a cheap augmented multi-touch whiteboard, or instant desktop sharing with any machine in the room.)
Hmm, if a rig like this could be scrounged together cheaply enough, one could form a community of such virtually linked hacker-spaces as a network! Maybe use daily round robin, or random pairing. And then, why limit it to just Boston or Silicon Valley? How about Houston-Atlanta for starters?
