I already experience a rise of pure Python 3 projects for Qt, and
expect even more at PyCon. New people to PySide and Qt will likely to
use Python 3 interface, so it will be nice to be ready.
What environment variables are conflicting?
We still have a chance to raise the question of specifying extension
path for both Python 2 and Python 3 at the same time before Python 3.3
Alpha is out this Sunday.

Is it possible to detect features and build them automatically if
available? This way everybody will be happy.
