The CCC (Computing Community Consortium) has an interesting article written by Ruzena Bajcsy (University of California, Berkeley) and Klara Nahrstedt (University of Illinoise at Urbana-Champaign) advocating the further deployment of high-bandwidth information-rich immersive interfaces to support collaboration and research activities.  What I find most interesting is that they propose to integrate it with a 4D Immersive holographic system.

D Immersive Holographic Spaces will be joint multi-view multimedia-rich spaces where people can immerse themselves in their physical full body size into a joint cyber-physical space with other people, and execute physical activities (e.g., physiotherapy rehabilitation), walk around people and observe detailed full-body social behaviors and communication cues of people in real-time, as if they were co-located in the same room, even though they are geographically distributed and thousands of miles apart.
