I like that: system-packages.

Ok, yeah. I think it would be a good idea for the package to somehow register itself as an upgrade to an existing system package. I still want the install command to install to site-packages, but whether the upgrade happens as an upgrade command or "python setup.py install -U" or some other mechanism is up for grabs.
