Hehe. I also had these thoughts, but I'd like to give two
examples:
* First one: Currently, the audio devices get ownership of the
first user logged in via PAM or a simillar mechanism.
Unfortunately, my girl friend wants to surf the internet. So
I open a second X session. Now she will not get sound because
the user of the first session uses the audio device.
Furthermore, I formyself use a second user to make the videos
(to have a clean desktop and to set everything to english).
So it can happen that I have three X sessions open, and I'd
really like to see that all three users can have sound.
* Second one: This case is somehow theoretic, but we have also
users on our machines which are not neccessaryly physical
users. In the future may be a shell script running as a
system user wants to inform me via audio that someone tries
to log in from an unknown host, maybe rendering a text
through embrola or playing a prepared audio file.
So, wouldn't something as a jackd running in root mode and
accepting audio from any user who is in the jack group be a
really desireable thing?
