It should also be possible to temper with the zipimport module to allow a
'scrambled' zip file. That makes it harder for users to access the code by
unpacking the zip file.

py2exe will collect pyc files into a single zip file and import that. It
does not need a driver script because it embeds the Python interpreter in
an executable. 

Yet another option is to compile the Python code with Cython and distribute
everything as compiled pyd files.
