There are technological ways to get the benefits of this approach without changing the office workers' habits.
I don't remember the name of the solution, but working with a big SF company which has both many office and remote workers, they had a camera mounted atop a TV in the meeting room. The camera would focus on and follow the current speaker even if they moved around the room, and the audio was clear as long as only one person talked at a time. It worked surprisingly well.
This is a cool trick but I don’t like it because when someone is talking I actually care more about seeing the rooms reaction rather than the talking head. The ideal solution (which I haven’t seen) is ultra high rez camera and software zoom on the client.
