I have used a lot of webcam and conference systems that are all designed to allow you to participate from miles away. Today I got to test drive, Beam from Suitable Technologies in Palo Alto. Emily from Suitable sent me an email with my invitation and a few clicks later I was 'beamed' into their sunny California office.
Beam is a remote presence device, think Avatar and Jonny #5. I was able to take over a robot, drive it around the office and interact with people all from the comfort of my desk.
Here is the video of my test drive:
