You are correct. Today, IP multicast is limited to a few small
closed networks. If we ever migrate to IPv6, this would instantly
change.
I am curious. Why do you think that ?

One of my previous assertions was the possibility of streaming
video as the major motivator of IPv6 migration. Without it, video
streaming to a large market, outside of multicasting in a closed
network, is not scalable, and therefore, not feasible. Unicast
streaming is a short-term bandwidth-hogging solution without a
future at high take rates.

Those numbers are reasonably accurate for some networks at
certain times. There is often a back and forth between BitTorrent
and NNTP traffic. Many ISPs regulate BitTorrent traffic for this
very reason. Massive increases in this type of traffic would not
be looked upon favorably.
The act of regulating p2p traffic is a bit like playing whack-a-
mole. At what point does it cost more to play that game than it
costs to build out to carry the traffic?
If you considered my previous posts, you would know I agree
streaming is scary on a large scale, but unicast streaming is
what I reference. Multicast streaming is the real solution.
Ultimately, a global multicast network is the only way to deliver
these services to a large market.
The trouble with IP multicast is that it doesn't exist, in a wide-
scale, deployed, inter-provider sense.
