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.

You are billing your content provider for the bandwidth consumption at his
port not because you intend to bill him for the bandwidth of content
provided, but for the bandwidth of content delivered to the end user! The
end-user is ALREADY PAYING for that bandwidth!

Something is *really* broken there.
