that's pretty impractical.  letting alone the type hell one would
have in porting a c compiler, i don't know of any 8 bit parts with
an mmu, and the avr is especially difficult, being a harvard
arch chip with program memory only in flash.

a more fruitful approach would be to write an assembler and
simulator, then an event loop to poll devices and serve an
external interface (9p or simplier, depending on how stupid
the chip is. :-)) which one could read from a machine with
more brains, a plan 9 box.

jeff sickel is working with pics and other tiny controllers.  see
the resonance tracking paper and slides at http://5e.iwp9.org/
and the work in progress at http://4e.iwp9.org/
