The problem with multicast in this application is that it only

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.
