How does this affect peering, when some providers want bandwidth ratios
in a certain range?
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.

I don't speak for anybody but myself - that's enough trouble.
