The 100 Gbit/s problem in your network

I don't see a need for multicast to work in Internet scale, ever.

Essentially multicast means core is flow-routing. So we'd need some way to
decide who gets to send their content as multicast and who are forced to
send unicast.
It could create de-facto monopolies, as new entries to the market wont have
their multicast carried, they cannot compete pricing wise with established
players who are carried.
