pywin32 ASP turned out to be EXACTLY what I needed.

It took very little effort to convert my CGI scripts, and the performance
boost was terrific.

There are a few nagging issues regarding the reload of modified modules.
The ASP engine often overlooks changed pyc files and therefore does not
reload the modified modules (this requires IIS restarts), however, it is
very good at detecting changes to the ASP files themselves.  I've taken to
debugging imported modules via CGI scripts to get around having to restart

Anyway, pywin32 ASP was an excellent suggestion... thank you Gilles.
