I'll wait for your mail about the pros and cons before getting further
on this. We'd need to rethink the gnome-sound-properties if PA was to be
used as a system daemon, as we wouldn't be able to easily switch
outputs.

What worries me as well is the amount of work necessary to get speaker
systems with more than 2 speakers (ie. stereo) working, and if it even
would with PA.

I'll hold on for more details, and you can fill in the blanks for me
then :)
