I do have source for the VR application (it's our home-grown VR navigation
tool).  I like this approach, although it will make additional demands on
the computer driving the VR application.

I've never looked at vic source.  Will it be relatively simple to extract
the H261 encoder?

   Well, if you have access to the source code for the VR application, you
   can embed the H261 encoder from vic into the app to convert the video
   buffer into an H261 multicast stream directly. 

   If you don't have access to the VR app code, you would have to pipe the
   output through a capture card of some sort.
