I'm not sure that this is actually right for pulse, but perhaps... that 
said, it quite nice that pulse can be totally replaced and transparently 
fitted in to e.g. an alsa setup that if you code this in pulse 
specifically, then it may not be that appropriate. If pulse does support 
it then I think it's wise that exploitation of this feature is further 
abstracted via a media library such as gstreamer.
