[pypy-dev] Who's developing language interpreters in PyPy

Hi, I've been reading up on pypy and is really interested in the idea of implementing X language interpreters in pypy, where X can be any known programming language. Do we have a knowledge of who is developing or interested in which X-to-pypy interpreter so there's no competition nor duplication of work? Personally I have some interests in a few languages that I know, such as R and pascal. Cheers maurice
