All we do is piggy back onto X11 forwarding built in to SSH. Overall, I'm not sure where you are running PA and why it needs to be system-wide at all (generally I would not recommend this), but come on IRC and then we can discuss and I can explain how things should be setup. I'm coling in #pulseaudio on Freenode. FWIW, I describe how the Remote X11 case works here: <a href="http://colin.guthr.ie/2009/08/sound-on-linux-is-confusing-defuzzing-part-2-pulseaudio/" target="_blank">http://colin.guthr.ie/2009/08/sound-on-linux-is-confusing-defuzzing-part-2-pulseaudio/</a> which may be useful reading.
