Funny that you choose multicast as an example.  I always thought that it
is a very rotten idea, and a security nightmare, too.

Distributed transparent caching does not require injection of any routing
information from customers into the core routing, and is a lot more
efficient than multicasting (i.e. you can always think of multicasting as
a caching with cache retention time set to nearly zero).

Recent years? :) ROFL :)
