nicholas negroponte's video vision

In his 1995 book "Being Digital," the then director of MIT's Media Lab, Nicholas Negroponte, talked about a telepresence project he was involved in (p121).

His idea was to project an exactly registered video of the subject onto the back of a translucent, life-size mask of their face. When the video ran, the impression of reality was impressive.

Could this be the future - or at least until holography catches up with videoconferencing?

Here's a quick graphic I whipped up to show how it works, with thanks to Rutgers for the animation faces:
