PyKDE
Well, just uploaded my hacked KDE 3.1 version of PyKDE to ftp://upload.kde.org/incoming/unstable/KDE3.x so it should propagate to the KDE mirrors soon.
It seems to work well, even if it doesn't expose ALL the KDE 3.1 API, and it should be useful as a stopgap until the authors release the real thing.
You can see a screenshot of it here
