Is there a way to specify which version of Python to use?  Ideally, I'd like to just make use of the Python interpreter setup by the py2app plugin if it exists, and otherwise setup a new environment by hand, but I'm not sure where in the Python API to look for this kind of functionality.  I'm not very familiar with the C interface to Python yet.

I'm not really interested in you working on that, either.  :-)  Multiple plugin developers using different methods to approach PyObjC seems like something that isn't likely to come up much.
