I got these nice boards from OSH park Thursday:

I only made one mistake (so far as I know):  the communication pins for the arduino are FLIPPED.  So these boards cannot be made backwards-compatible with NGT20 anything.  Other than that, this board seems to work great!

I will be porting #Arduino Desktop to this soon.  I just need to make sure the keyboard pins are right and I need to hack the Arduino library for communicating with the NGT20 for compatibility with the error on the PCBs.
