I'd have to think about this further - my most recent experiment with 
selling hardware almost didn't break even. If someone else wants to run 
a group buy however I'm certainly not opposed to it.

At any rate, there's currently plenty of unused I/O on the processor and 
a bit of empty space on the board. It might be possible to squeeze a few 
extra goodies in. Depends on what people want. An I2C serial EEPROM 
would probably be pretty easy to add but an audio CODEC takes a fair 
amount real-estate so it would have to be justified by reasonable demand 
from the community.

I'll fix the errors in the present board and consider suggestions for 
minor changes if anyone has any.
