Not sure what you mean by this?

Unless you use virtualenv as Guido suggested in the other thread ;-)

If sitecustomize.py had more uses that the setdefaultencoding hack, I'd
argue more about this... If it does have other uses, my argument would
be that "site" wide is a very subjective term tht many people, myself
included, would like to be able to mean "per project, I don't *ever*
want to screw with my actual Python install, it should stay pristine"...

Agreed, but I think that's only an issue when you're starting up an
interpreter. If you're running a script from a file or module, I'd say
it's more akin to what's specified in PYTHONSTARTUP being executed that
than a random script being silently executed without your permission.
