This isn't a take it or leave it deal. To start out and branch out, most
streaming is VOD, which even within a cable network eats up huge amounts
of bandwidth. In the end, it's expected that there will be a mix of
multicast and VOD.
Watch the game live multicast. Missed the game? Watch it on demand. As
things progress, we'll probably see more edge content delivery systems
(like Akamai) to cache/store huge amounts of video for the local
populace. It won't be every movie, but it will be the ones which have a
high repeat rate to ease traffic off critical infrastructure, saving
everyone money, making everyone happy.
What would be really awesome (unless I've missed it) is Internet access
to the emergency broadcast system and local weather services; all easily
handled with multicast.
