Better performance with Erlang multisend?

[benbro]

There is a discussion and PR for multisend support - being able to send the same message to many pids. Might help with MUC for broadcasting the same message to many clients in a large chat room. Do you think it is relevant?

I think we do privacy check for each user before broadcasting + some extra outing logic. So, it could be potentially tricky to add, especially into muclight.
