At iRobot we make extensive use of our AVA 500 Telepresence Robots.  Last week, for the first time ever, we had a meeting with two participants attending via AVA.  I have proposed an idea for a cartoon which has a bunch of AVAs sitting around a table having a virtual meeting.  If I ever find a free moment at work, I may orchestrate a photo of exactly such a scene.  I think it would be really funny.
