And, more to the point, as we proceed more and more into a live-tweet,
social TV world, *having all your viewers within a second or two of 
each other* becomes more and more important.

My experience is that that's *much* easier to manage in a multicast 
environment, than with live-unicast streaming -- especially when there
are multiple server clusters in different places for load balancing.
