The problem with multicast in this application is that it only works if all the clients are accepting the same data stream and viewing it live.

That's not how people tend to view Web video, there might be 50% of the crowd watching it as Oprah speaks but the rest are likely to be time shifted from a few secs to hours or even days.

FYI, in this case of Oprah's Book Club, it was 500,000 people trying to view the webinar *at the same time*.

The web collaboration sessions are then archived on her site so that people can view them at a later time.  So some % of viewers will watch them at some later time, but 500,000 were trying to participate in the "interactive" and "real-time" web collab session.
