I got ya Colin, good point. I can't be certain that will help some, not sure people are using computers/devices that can handle all that bandwith at once. I mean that the chat is sometimes causing problems with bandwidth (or other issue) when say 6 people are always broadcasting voice. I was thinking maybe that issue could be helped or reduced if there was a push to talk button.
