Note certain, but it's likely that site.py is imported even under
PythonWin.  If that's true, and it should be easy to test, just
create a file in your Python directory with an extension .PTH,
and place within it the name of the directory you want added
to sys.path.

For example, in my directory n:\a\python, I have a file 'lib.pth'
that contains the single line 'n:\lib\python'.  Every time I 
run a script, it adds this to the end of my sys.path.

Beats editing the registry, too.

Yes, registry.  Grim but possibly the only place PythonWin can
find it.  Not sure.

Doesn't your Windows support adding lines to config.sys, such as:
   shell=c:\command.com /p /e:4096
which would extend environment space to 4K?
