[Python-Dev] Python merge module

Is there or will there be support for python merge modules so we can include python in our installer? Also, the discussions I saw about windows installers not removing the path on uninstall is completely false as regards the installers that wix creates, at least. I've modified the path many times and explicitly tested that it was removed on uninstall. I can't speak for the msilib package and what it does - perhaps it's doing the wrong thing? But has there been thought towards migrating away from msilib and using platform standard tools such as wix (used by ms office, visual studio, etc.)?
