isapi-wsgi - An ISAPI WSGI Handler
http://code.google.com/p/isapi-wsgi/-- Shared with Google Share Button
This is a wsgi handler for Python scripts which I was able to use successfully with older versions of Mercurial's web server script. No details on the implementation at the moment, except for the fact that I was able to model the Mercurial script's installation on the test installation provided by the wsgi handler.
