crossplatform standalone python apps

[Gabriel Rossetti]

Hello everyone,

I like to create a cross-platform standalone python application, like 
Mac OS *.app dirs. The idea is to distribute a zip file containing 
everything (the python interpreter and all) so that a user just unzips 
it and runs it. Has anyone ever done anything like that? I searched 
google but didn't find anything really, and currently, even in my dev 
env, I have to set the PYTHONPATH manually, and for a standalone app I 
couldn't do that for example.

Thank you,
Gabriel
