I'd say we write a startup program which sits in the same
directory as the python15.dll (which is the Python
directory for my customers! I don't want to interfere with
anything.) This extracts it's executable's program path,
chdirs to there, sets the environment internally to "."
(which holds now), and the site.py trick always should work.

We (PNS) go even further (but at the moment without the extra
.exe which we will do soon). Site.py does some fiddling with
the Python path, tries to find ./lib and so on, and then
looks for ../app.py which has to be there. From there, the
bootstrap loads the application.
By this, we can replace the whole Python installation
by moving a single directory tree. It does not contain
any application dependant stuff and just knows that
the app.py sits on top.
