I have only tried vbap briefly. A good thing about vbap is the possibility of 
placing speakers in a setup message. I have hardcoded these positions for 
now. I have not tested the positioning

I am using power panning with some filtering and reverb(s) to simulate the 
sound in the virtual room.
The externals takes object x,y,z,camerax,y,z and cameraanglex,y,z (angles are 
computed externally from GL eyepoint, lookat and upvector positions to reduce 
the net data amount). The externals outputs channel levels (with distance 
calculaion), distance (used for calculating doppler) and a normalized z value 
(-1->1) in 2D speaker setups (4 and 5.1) which I plan to use for some 
binaural filtering experiments to simulate vertical positions in these setups.

Filtering and reverb is done in standard PD (or other libs) objects.
