If you have an OLPC — or have set up VMWare or another environment to emulate one — and you’re in the Silicon Valley area, there’s a group of enthusiast hackers forming called [SV_OLPC][1].
I ran into the founder of the group completely randomly after leaving [NSCoder Night][2] a couple weeks back, and it’ll be interesting to see just who is doing what with the OLPC stack.
