That really depends. In the mid-term this should be possible, and one of
the things missing is indeed a better assembler backend (since right now
we have no float support at all). Note however that PyPy doesn't support
Numeric Python, so depending what you want to do this might be a problem.

I guess there is no reason, apart from the fact that it sounds a bit
unfair to other students participating in SoC. What I could imagine is
having a sprint during the SoC-period and asking that company to pay for
the travel of the student or something similar. If you are concretely
interested, you might want to take it off-list and discuss with the
caretaker group: pypy-ct at codespeak.net
