Lpc2000

Odd comment. I doubt that they consider their code to be Random. Other 
Microchip implementations have been reliably functional, if not always 
awe inspiring. Their USB, TCP/IP stuff etc is solidly boring. I would 
rather trust this than some $18k package that may very well have been 
brewed up by a hobbyist. just because it's a commercial offering doesn't 
mean it's reliable, I mean look at windows, the PSP, etc etc.
