I can also see how this affects the ISPs providing bandwidth to the content providers. In our colo for example, we rate-limit customers to the paid-for bandwidth at the colo port. With multicast however, they could use significantly more bandwidth, because every router in our network could potentially send the stream to many ports.
Only if you're using hubs or dumb switches. If your switch is multicast aware, the multicast traffic only goes to ports with active listeners for a particular group. Routers send multicast traffic only if there are active downstream listeners (where "downstream" doesn't mean the same for unicast as it does multicast).
