I *thought* (relative Mac newbie), the standard advice was that if you

My understanding is that if there is a system Python, you shouldn't change it. Ever.

System Python's are for other components of the system; you can use them, but shouldn't modify them. Including installing or updating packages in the site-packages directory.

At Zope Corporation, we use a clean Python for all development and deployments. Nothing gets installed into the site-packages, because different applications want different packages (or different versions), and we want to deploy with what we test with.

Meaning that you have to maintain two Python installs - something that
hasn't been a problem for me yet. So even if Mac OS ships with Python 2.6,
many users will still want to install their own version.

Indeed. I've never had to do anything to maintain the system Python on Mac OS X. It's there, Mac OS X does what it will with it, and I use my private (and squeaky clean!) Python installations.
