Could multicast be supported in the future？

[Geker]

Great project!
It would be even better if UDP could support multicast reception and relayer

Maybe not, for example:

What if the multicast targets respond differently? like:

request -----multicast -----> {target1, target2} , but, they responds {resp1, resp2} , where resp1 != resp2 ?

And if you really need redundancy, you could start multiple instances like:
groupA: relayer1 -> relayer2
groupB: relayer3 -> relayer4

And the client program selectively send the packets to relayers.
