There isn't much there really. The idea is to make glib listen to PA's 
file descriptor and use glib's callback system for integration.

Well, maybe if someone already wrote code for Motif apps to use ALSA, 
that might be easier. The ALSA API is quite stable now, while Lennart 
has said not so long ago (in the Skype-wanting-to-use-PA-natively 
thread, IIRC) that the PA API could change.

Maybe going in that direction could be easier for now :)
