No insult was taken. This appends to PYTHONPATH, doing it the other way 
around is probably better. I'll check-in a patch latter tonight.

BTW. There is no need to convince me about using Python instead of C :-)

Sounds good, but how are you going to deal with moving the .app bundle 
when not using /usr/bin/python? '#!../Resources/python-interpreter' 
probably won't work. Standalone apps are probably the most important 
for not using a python-based main.
