That would be awesome. One update to the pics and stuff I have so far, During the xilinx programming stage, I used a chip carrier socket in a breadboard, powered by a 5v wall wart, because I happen to have a bunch o those sockets. I'll send you a socket or a few if you want, but I would say, ditch that and just use a M100 itself to power the board for xilinx programming. You need a M100 to do the final flashing anyway, not to mention testing, so it's a no-brainer, just pop it in the m100 and let the m100 supply the 5v to the board. Perfectly fitting socket and 5v supply ready made.
