Hi Robert, Sorry for the delayed response, I did not read your e-mail until today, gmail messed up the notifications :(
Regarding the multiview approach, it doesn't matter how you set the layout, I usually use a grid because is more compact when doing the RTT. The stereo computing is always horizontal as the current displays only support horizontal parallax. So answering your question, Yes, a callback per slave computing each frame the matrix offsets should be enough. I was using a similar approach.
