This is a little presumptuous on my part, but what other reason would
motivate a migration to IPv6. I fail to see us running out of unicast
addresses any time soon. I have been hearing IPv6 is coming for many
years now. I think video service is really the only motivation for
migrating.
I am wrong on plenty of things. This may very well be one of them. :-)

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

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.
