Very nice writeup!

At some point I need to add to that a small tutorial on creating Python 
distributions and developing/testing with virtualenv and setup.py develop.

Not that there isn't other documentation out there, but a lot of it is 
outdated or incomplete, and doesn't address all the issues that might 
come up in packaging science software.

It's far too often that I *still* see people doing things like

sudo cp foo.py /usr/lib/python2.7/site-packages/

Yargh!
