Sorry for the buzzwords. What I meant was: there are whole classes of people who are very used to using Justin.tv (and ustream to a lesser extent) for live video. Maybe some of them would switch to Google if YouTube suddenly offered live streaming, but my feeling is that this is a Twitter vs. Google Buzz situation. Google can offer, but if the digerati are already used to another service, they won't necessarily switch. Justin.tv is kind of a dark horse -- ustream may be better known, but Justin.tv is actually bigger. The Justin guys can probably explain this better than I can. :-)
