That makes sense. Adding a new daemon is not a desirable solution, and
sound events do conceptually fit into the tasks the notification
daemon takes care of.

Well, that proved to be less painful than I expected. Not everything
worked (notable exceptions include mozilla and nautilus), but I have a
CVS build now in which all the relevant parts mentioned above work.

So here's what I will do. I'll take some time to study the relevant
code and docs and maybe tinker on the CVS build to get some more
things working. When I work out what can be done and what I think is a
good idea, I'll raise the topic on desktop-devel and we'll see what
comes out of the discussion there.

Last but not least, Nickolay, thanks for your help.
