We are working on it. It will be out with or before the next User's
Guide, probably in a few weeks. It will be on the web.

Depends. On a single processor (and assuming that VTK support the
stereo mode you are interested in), it would require a few lines of
change. It is also easy when running in parallel and using collect
(rendering locally on the first process). However, running in parallel
and using sort-last compositing, it would be a lot tougher. I think the
z-buffer is handled differently when in stereo mode and the compositing
code has to be made aware of this.
