I'm sorry, I failed to mention that all my projects will be open source so preferably all the libraries should also be so. My bad.
The thing about Python-Ogre is that it is almost the perfect solution for me. I have only two major issues:
1. Horrific difficulty to get this to work on any Linux. Even Ubuntu doesn't have an official package or any PPA for that, or at least I failed to find one.
2. Apart from the completely one dimensional audio library in PyGame, I couldn't find any other audio library that would be still supported. PyGame audio library forces you to calculate sound positioning and distance yourself and it only supports mono and stereo, no surround. In the end I can accept these obstacles and limitations, but I would prefer not to have them in the first place.
