A recent customer uses multicast to have the same packet arrive at multiple destinations at the same time for resilience (their own internal systems, not IPTV or media etc). Having just refreshed their network for the next 5-10 years it's not going away anytime soon.
I believe the same time delivery is motivation for stock exchanges too. One of the larger exchanges used MX and multicast, which of course does btree or utree (in this case utree) replication, which makes delivery times are very much variant. So it is very much implementation detail what type of delivery time differences to expect in different ports and it is not by design superior to unicast. -- ++ytti
