Hi Eric

New ports of V8 are always welcome, but as long as you are experimenting
with getting things up and running I suggest that you work in a repository
of your own. This is how the MIPS port is currently being developed at
http://github.com/paul99/v8mips. When you have something substantial (e.g.
assembler/disassembler/simulator) up and running we could start looking at
adding it to the V8 repository.

Regards,
Søren
