"Project Ghost uses videoconferencing technology Logitech already sells, pulls a trick like what you might know from a teleprompter to create the projection"
This means all you get is the same, 2d flat webcam image of the other person, but semi-transparent and "floating" in the air.
Some people will likely think it's cool, but I want something at least stereoscopic if not pseudo-volumetric, which is what I think Starline does, via heavy processing.
Sounds like HP Halo, but with the ghost trick.
