What errors exactly do you get?

Although I have posted before that this wouldn't work, currently I
believe that it *should* work.
I tried the 'simple' sample in the py2exe distro, which contains a
trvivial command line program, plus a simple wxPython program, wrote
them to an ISO level 1 CD, and it worked.

1. The python modules are imported from the zip file, as long as this
has an 8.3 name, all should be fine.

2. Extension modules are loaded with imp.load_dynamic (custom loaders
are created for them, in py2exe\build_exe.py, the create_loader method).
As far as I can see, imp.load_dynamic(module_name, file_name) should
work independent of the case or spelling of 'file_name'.  If the
extensions you need have filenames with more than 8 characters, you
could probably subclass the build_exe command.
