Thanks! I'm currently designing a case. I may end up making a limited run to sell, but I very much plan on making the code and design files available to others in case they wish to attempt this themselves. That said, the entire affair is all surface-mount parts placed very closely together. It's tough to assemble by hand, as I currently do :)
The decision to use native IO for the USB communication was motivated by a few early design hurdles - there's literally no room for an FTDI interface chip on the board, and I did not want to deal with FTDI's host-side drivers, which I have quite a lot of (bad) experience with. I got my atmega328p parts from element-14, which is one of Farnell's multitude of webstores. They show as perpetually out-of-stock, due to the high demand from Arduino folks and the historically low market availability of Atmel parts since they closed a few fabs. Placing a backorder request generally works much more quickly than their lead time implies, the last time I bought these parts it only took about two weeks. I considered buying parts via eBay, but apparently some shifty "entrepreneurs" have been floating knockoff 328s there and I did not want to take the chance. The AVR codebase, EAGLE libraries, project files, and host-side interface code are all currently available at http://www.github.com/koolatron -- I haven't pushed to the repo in a little while, so the code is likely out-of-date, and there is no documentation as of yet.
