Dear Jeff,
  While I haven't used a demultiplexor for this purpose, there's a group
at NCSA that runs VMD in "side-by-side" stereo mode on a Linux PC with
dual display outputs (with graphics window using the entire display area)
which works well. If you have a Mac with 3 video outputs this would
work well (one to use in controlling VMD, and two to be projected with just
the 3-D image displayed...) We use Sun workstations with multiple outputs
to drive our projection system here with active stereo, with the GUI on
the non-projected display(s) and with the stereo display projected. I could
just as easily setup a system with passive stereo using the same hardware.
I suspect that the main difficulty you'll have is getting a Mac to have
3 video outs. The current VMD binaries don't contain the magic to cause
the Mac to run in stereo-in-a-window type stereo mode required by the built-in
code in VMD, so the multiple-output method is your best bet until I conquer
some of the sticky OpenGL Extension problems on MacOS X.

Does anyone else have suggestions here that I haven't thought of yet?

Thanks,
  John Stone
