Holographic meetings are now

This is the next generation of teleconferencing - telepresence via holographic meetings - where people from somewhere else in the world appear right in the room with you (or in this case on the stage).

All using internet IP-based standards.

Think of the travel savings!

No sense of smell yet though!
