I was home sick today, so I tuned in between consciousness I tuned in to scoble and jeremiah's live feeds from the Web 2.0 conf. It was quite interesting. I saw Dell's Lionel Menchaca come up and talk to scoble, and I saw scoble setup and shoot an interview right in front of us (I forgot the name, I think sharebook or something similar). Their were times when the signal wasn't good and we got choppy video/audio. But when scoble moved to the lobby the signal was good and the interview was pretty good. Almost as good as being their, at least for the parts I was awake.
This live tv thing might have something to it, at least at conferences.
