I thought of a fun idea, that would involve a lot of money pouring into the foundation Especially if we can get some form of openCL, then the Pi would really make a great system for making a cluster computer with.
Two things that would make this a lot easier:
A rack to mount several Pi's in. I'm thinking you slide it into a slot that plugs in the MicroUSB power and the SD card (or the fake connector, see below) then when you close it it connects the LAN as part of the cover that holds it in. It wouldn't be held up by the connectors, there would still be ridges it mounts on (not unlike a CD drive mount)
How hard would it be to make a Computer imitate being an SD card? As in, there's a connector with just the pins leading in that run to a few GPIO on another Rpi. This would allow having, say, 20 Rpis behaving as the SD card emulators for another 40. They would load then run on RAM, recieving work over LAN. This, ideally, would save some money, as I can't find anywhere with a decent supply of cheap, low capacity SD cards.
best part: We could fit 60 Rpis in a Full ATX tower space with plenty of breathing room, and still drawing significantly less. Also significantly more powerful in the right applications.
