since i was just playing around with pulseaudio recently, here some hints:

- in /etc/pulse/client.conf, you can set "autospawn = no" to prevent 
pulseaudio from starting again and again.

- you can run pulseaudio on top of jack, which means that those 
applications that want to use pulseaudio can use it, but others are not 
effected. (i recently decided to make this my default configuration on 
desktop machines: it allows me to watch vimeo and at the same time 
fuddle with Pd :-))
