Sorry I'm not with you there, I had suggested no video (either RT or not) due to the required bandwidth. I would have invisaged text only, even audio uses additional bandwidth over text. I was originally thinking of something more social, for those who do not sit on a laptop beside their scope. For example someone getting ready for a nights viewing and checks the group to see what others are looking at. This would offer up a live group view but with the users being spread across a much wider area than a traditional club. There would also be the chance for imagers to review settings and techniques while pointed at the same target.
