Cisco have established a strong presence in the market with their design for a purpose-built room (generically a videoconferencing suite):
The Apple iPhone 4 has a forward-facing camera and a built-in application / service called FaceTime
Or if you're not at your desk, just leave your iPad there?
Or maybe you'll have a telepresence android?
So there's a range of options there, and we'll see which approach proves to be popular. The fact is that the internet is mostly (in volume terms) used to transmit video, bandwidth is the easiest internet parameter to increase, so this is going to lead to significant developments before long. This particular post is intended to illustrate the 'physical' end of the meeting, e.g. the picture of the guy sitting at his desk so you can walk in there and talk to him. Obviously the 'user' of the telepresence device is sitting somewhere, using some equipment, and this could be the Collaboration Station or something like it. When everyone is using a collaboration station, then these 'physical' versions become less needed.
