One of my requirements is encryption of the pyc files. (I need -some-
degree of basic protection against decompyle and the like.) The file
in the archive needs to be encrypted and only decrypted when it comes
to be imported. This looks like only being about 3 or 4 lines of extra
C code (given a standalone encryption library) if put in the correct
place.

Sadly Python is my 2nd language, and these distutils scripts in
general are possibly the most complex (or at least idiosyncratic) code
that I've seen. I understand very little of it. :)  And wouldn't know
where to start altering it.

Ok. I don't need to do this urgently, but Win98SE is going to be both
a key development and deployment platform for me.
