Maybe Java OS might be more specific and practical :) . Anyway ,it is
on my ToDO list.

if you wanna do hardware acceleration ,we could consider libJIT which

Yep,both Kaffe and JamVM are good thing to learn. What kind of
applications would you want to run on AVR32? On low-end devices,enable
JIT would be expensive.
Now that JamVM is working on AVR32,maybe we need some benchmark or
something.
I have said that I would be glad and interested to help a fresh port
on AVR32 ,so i think JamVM would be fine..:)

That would be great.... There should be many experts here.....:)
