[Mono-dev] Mono port to AVR32 Linux

Thank you Rodrigo,

I don't *need* to port to the AVR32 I just think it would be a fun 
project.  I like the AVR32 architecture and just recently picked up a 
development platform for the AP7000, I've been using their ucontrollers 
for quite awhile.

The alleged performance advantages are impressive, 50% code reduction 
vs. ARM and 35% performance advantage over ARM11 at the same clock.

One interesting AVR32 feature is hardware Java bytecode execution, I 
don't know if the port could take advantage of that or not.  It would 
most likely require either translating your IL to Java bytecode (like 
grasshopper) or creating a Java bytecode JIT; both of which would kind 
of defeat the purpose of mono.

I will take a look at Linear and work from there.
