Yup, UNC is working on this as part of their Office of the Future initiative (Henry Fuchs is lead on this).  UNC is part of the NTI, that's why you saw their work in that context.

Takeo Kanade has been working on a similar system at CMU.  His Virtualized Reality project was the basis of CBS' implementation of EyeVision for the Super Bowl.

  I attended a lecture at The University College of London (UCL) where the speaker mentioned just such an application.  Apparently a big problem is flat featureless surfaces, this can be overcome by using a mixture of ambient and differed (imperceptible and structured) light which allows the cameras to extract the data.  The project described was a part of National Teleimmersion Initiative (see http://www.advanced.org/teleimmersion.html) and designed to adequately test the capacity of The Internet2 (see http://www.internet2.edu/).

  I hope this is useful.

  Hello, 
  I haven't yet had the time or ready resources to fully develop this idea, 
  but I'll throw it out anyway:  Input devices---  Array of synchronized 
  cameras/infrared sensors linked to camera locations in a 3d scene 
  providing realtime user input in the form of a 3d mesh, which could then 
  be procedurally textured from camera input bitmaps.  Drop the polys a bit 
  and its suitable for network transport.  Output could be achieved via 
  voxel technology.  Result:  Holographic teleconferencing... as a sample 
  app. 
  Enjoy, 
  Scott

  Time and spacedripped dense together as crystalline visions coalesced 
  into matter before me, folding lucid blue, shining, then inverted sleekly 
  into a polymer hallucination of totality.  Soft faces rose from the 
  surface of pooled reality, it now only a minute portion if perception, a 
  slim sliver of selective imagery, to speak great questions of their 
  existence.
