I don't know, but sending audio over a network sounds like the sort of use case that requires a sound server. Playing sound locally doesn't. Although, as I said elsewhere, I have mpd stream to icecast for playing my audio remotely so, in my case, I don't need pulseaudio for this: I imagine you could configure a similar setup where anyone on the local network can register with icecast as a "radio station" znd stream sound that way.
A workflow that enables network transparency by using a tool for radio stations might work for music, but not for anything with latency requirements. Imagine playing any video game with even a 100ms audio delay.
