Exactly. Does it support redirecting audio streams to another machine on the same network? That's a vital feature in our hackspace, where everyone can send audio to the room speakers via PA, and it's also used extensively in my living room (where the speakers are connected to the home server).
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.
That's something that really bothers me about pulse: it looks like it should have a nice unixy design and work well, but actually using it is, in my experience, a complete potshot.
For me the important advance was redirecting an audio stream to a different device on my machine, as I wanted to happen when I plugged in my USB headset. Currently that works more smoothly on Linux for me than Windows.
