[pymvpa] Why no PyPI?

See, I knew I was stepping in it :).
I think I can handle that. Pip only does python stuff, of course, but that covers the must-haves and the strong recommendations. For the optionals, there's a way to define external requirements, and print a warning saying, "you should really consider installing this." I found a decent example of something that might be acceptable in the python module Shapely. See this gist for an example of what happens when you try to install it without a c library that makes it run faster:
Would that kind of behavior be acceptable? If so... yeah, I think I can take this on. Otherwise, I'll at least be happy to write a homebrew formula, but pip wouldn't make a whole lot of sense.

But it would make using PyMVPA along with virtualenv a lot easier across platforms. Some tweaks to setup.py to add the dependency list, and hey-presto. Or... that's how it seems.
