Just as a data point. I have used mpi4py before and have built it on many systems ranging from my macbook to NERSC supercomputers. In my opinion it is currently the best python mpi bindings available. Lisandro has done a fantastic job with this. Also Fernando and I have worked hard to make sure that mpi4py works with the new parallel capabilities of IPython.
I would love to see mpi4py hosted in a public repository for others to contribute. I think this would really solidify mpi4py as a top notch mpi interface. But, my only concern is that there might be many folks who want to use mpi4py who don't need scipy. I am one of those folks - I don't necessarily need scipy on the NERSC supercomputers, but I do need mpi4py. Because of this, I would probably still recommend keeping mpi4py as a separate project. Is there any chance it could be hosted at mip4py.scipy.org? I strongly encourage others to try it out. Installation is is easy.
