I don't know if you actually want replies, but I'll bite.  I have pypy
installed (from the standard Fedora pypy package), and for a particular
project it provided a 20x speedup.  I'm not a PyPy contributor, but I'm
a believer.

I would use PyPy everywhere if it worked with Python 3 and scipy.  My
apologies if this was just a rhetorical question. :)
