Retailing at $80,000 for one screen and $300,000 for three screens, Cisco's telepresence technology simulates the act of actually being there, which is way better than traditional teleconferencing. The whole setup is backed by a supercomputer, three plasma screens with 1080p/30FPS video, and is SIP based, running over an IP network. You can fit two life sized Robert Scobles on each screen, plus Cisco comes and installs it for you.
This isn't anything regular consumers can go out and purchase, but you can try and get your company to hook one up for communications across different branches.
