Indeed, I think this is the easiest part to do.

I think that since we are highly compatible with CPython, existing 
Python apps are likely to work in pypy-jvm, modulo the fact that we 
still miss many libraries.

For example, as Jean Paul said he was able to run a twisted IRC bot 
using pypy-c; I think/hope it to work also on pypy-jvm once we have 
implemented modules like socket & co.

The JVM backend has been mostly written by me and Niko Matsakis. At the 
moment both of us work on it in our spare time, but if my phd proposal 
gets accepted I should be able to work on it much more continuously.
