Proving the only general rule is that there are no completely general rules.
Trading is an obvious multicast application. Video distribution, for
distance learning or conferencing, is another. Incidentally,
practical videoconferencing is rarely any-to-any as many people
assume. Think about it. Are you going to be watching the musician, or
the entire audience? [1]
I've found a disconcerting habit of a number of medical applications
to broadcast (not multicast), apparently because they were
proof-of-concept, slapped-together code in a small lab LAN and their
financial people decided to ship the alpha.
[1] That can depend on the audience, but that is a phenomenon more associated
with concerts than distance learning.
