I know someone that used ustream.tv to broadcast several programs at a recent computer conference in Florida. Quality of the images was not great, but they could be used, and because of that I am active again in Second Life and Tech Soup's Non Profit Commons.
How can we do what was requested, if the source of the video is on Second Life and the viewers are in RL.
Conversely how do we do it if the source is in RL, but the viewers are in SL
