You're wrong. :-) ISPs have no plan to enable multicast -- ever. IPv6 "supports" multicast, but it can't force anyone to turn it on. See previous discussion: http://news.ycombinator.com/item?id=443599

IPv6 makes routing packets harder, not easier.
Care to elaborate?
I see people are saying that the hierarchical address-assignment is to some extent going out the window, but apart from that, how is IPv6 routing going to be a bigger mess than the current IPv4 routing?
Hopefully IPv6 and global multicast should solve this once we finally rid ourself of this ancient thing called IPv4.
Someone please correct me if I'm wrong.
