I hadn't thought about running the entire backend in the VM.  I wasn't sure it would.  Or maybe it was just frontend that doesn't?  I need to go back and review the wiki again...  In any case, it's interesting prospect.   I'm not sure if VMware or Virtualbox would be better.

Good to know.  Both products are supposed to provide OpenGL hardware 
acceleration.  Has anyone tried OpenGL playback in a VM?

Yeah, that was poorly worded.
