I am not sure if a pure QRM implementation would be worth it, but I 
have to look more into this... anyway, the most interesting part would 
probably be the RenderMan shader language.

I agree. As for me I am mostly interested in doing research in the 
fields of advanced rendering techniques and related, geometrical data 
representation.

This is my idea as well - to make the kit be a foundation for 3D 
graphics which can easily be customised for personal needs. Thus I also 
decided to remove some functionality found in the old 3.x 3DKit as it 
can easily be integrated on top of the core 3DKit (ie. LOD groups, 3D 
sound rendering, switch groups, ...).

You have some spare time? Where did you get this from...:-)

If it is additional stuff, yes why not - esp. having more physics 
functionality would be cool! As for the current C implementation, I 
think it is quite well optimised, but then there are always ways to 
improve...
