There is that, and the MPL, which is couched in terms I'd need quite a few 
hundred bucks worth of legal advice to translate.  Couple that with me 
having to cram the assembly nemonics for a cpu I always considered a little 
dain bramaged, and I believe I'll pass & let someone younger take a shot at 

Personally, I'm more inclined to want to check out the WizNet 3150 kit, it 
sounds pretty decent on paper at least.
