Are there any?

I've set out to make an adventure game and now I'm trying to find a set
of python-modules to help me do that. I know of the usual non-python
suspects (AGAST, AGS, Wintermute, ...) and while I they are really good,
I'd like one that is cross platform.

I've found pyScumm and pyAdv but both don't seem to be ready for use
yet. So are there any "usable" engines written in python?
