Although I can recall working on a product that delivered satellite multicast streams (with each multicast group corresponding to individual TV stations) to telco CO's. This enabled the telco to implement multicast at the edge of their networks, where user broadband clients would issue multicast joins only as far as the CO. If I recall this was implemented with the old Cincinnati Bell telco. I admit there are a lot of CO's and cable head-ends though for this solution to scale.

I don't see how multicast necasarily solves the netflix on-demand video 
problem. you have millions of users streaming different content at 
different times. multicast is great for the world cup but how does it 
solve the video on demand problem?
