But the *load*, while admittedly lessened over unicast, falls *mostly* to the carriers, who cannot anymore bill for it, either to end users, providers, *or* as transit. Will they not complain about having their equipment utilization go up with no recompense -- for something that is only of benefit to commercial customers of some other entity?
Why would they bill someone for a service they are already providing? So the first user in a router tunes to a multicast stream. Consumption for the ISP and all the routers in the chain to the source: same as if it were a unicast stream. Then a second user tunes to a multicast stream. Cost for the ISP: zero. So 5000 users connect each to a different multicast source. It is the same as if they all used unicast. The utilization can never be worse than a unicast-only network. So maybe I'm oversimplifying, but I fail to see a problem, only an artificial one created for the sake of it. Other than the potencial CPU load of the routing protocol, I even fail to see the commercial value of not providing multicast.
