I just wanted to follow up, it looks like the Vista installation issues have
been ironed out with the release of python-2.6.1. I was able to install
32-bit python-2.6.1 from the msi file distributed at python.org in a
straight-forward manner, no need to mess around with user account controls
or other such nonsense. I even have setuptools working with python 2.6, I
built and installed a setuptools msi without much trouble (distutils just
doesnt like setuptools version numbering).

One pleasant surprise: python-2.6 is built with visual C++ 2008, which has a
free express edition available so building python extension modules might be
a little more convenient than it was in the past.
