If we're really talking efficiency, the "popular" stuff should probably stream out over the bird of your choice (directv, etc) because it's hard to beat millions of dishes and dvr's and no cable plant. Then what won't fit on the bird goes unicast IP from the nearest CDN. Kind of like the "on demand over broadband" on my satellite box. Their selection sucks, but the model is valid.

I think this shows the need for an Internet-wide multicast implementation.
there's a pretty longtailed distribution on what people might chose to stream. static content is ameniable to distribution via cdn (which is frankly a degenerate form of multicast), but lets face it, how many people watched "Charles Mingus: Triumph of the Underdog" in east palo alto last night at 10pm.
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.

Somebody should invent a a way to stream groups of shows simultaneously and just arrange for people to watch the desired stream at a particular time. Heck, maybe even do it wireless.
problem solved, right?
