I personally find the networking aspects of Pulse to be quite handy. I have mpd running on my file server, streaming to a PulseAudio server on my media center (Ubuntu Jaunty). I also have it stream to my desktop.
Using the nifty iPhone app MPod, I can control my playlist from the palm of my hand, in a fashion that beats a universal remote all hollow, since I can actually see the playlist I'm queuing, instead of having to squint at the screen (yes, I have a small display, don't laugh) or get in position to view the screen. And there's nothing like being able to switch tracks while you're on the can (there's a joke in there somewhere, but I can't quite find it).
I hope to one day figure out some sort of motion sensing or proximity detection mechanism to selectively enable/disable mpd outputs so that I can be listening to music on my sound system, and when I leave the room and into my office I can pick up my headphones, and the same playlist will be playing there automatically. Sort of like motion controlled lights, except it's sound.
I'd also really like to see is some kind of mashup between vlc's remote control app and Moovida and this MPod app, so I could have a centralized media center with a truly universal remote control. Apps work on the iPod Touch too...
