"The protocol consists of two parts: administration... and a data
transfer..." Same old story. Should it make a difference that the
receivers are in a multicast group, or is that just a pattern that can
be abstracted away at another level? Certainly, some optimizations
exist using the knowledge that the transfer is to multicast receivers,
but fundamentally isn't this Yet Another Transfer Protocol?
