crossplatform py2exe - would it be useful?

I've tried Freeze before, but I'm hooked on py2exe because it's so
SIMPLE and flexible, and handles all the weird cases automatically...
For those of us that aren't C gurus, anything that makes the process
easier is welcome.
To clarify your proposal, would you simply build the executable using
the same setup.py script on other platforms too, or would you have to
do more manual steps?
Thanks for the great work so far... py2exe ROCKS! q:]
