1. default Mac from a company
2. open a terminal and play an mp3 with mplayer as normal user
3. going to another PC and logging in with ssh (as root) and playing
an mp3 ) -- works
4. again going to another PC and in order you cannot blame it on login
as root I added another user and played back another mp3 -- it worked
too
in any case 2 different users were playing back the mp3.

maybe iTunes is requesting this, but then hey this option would be on
enduser application level and not at audio stack level.

Seen from my side setting this option (the possibility to lock audio
to one user) on App level instead of Stack level this would be much
better.

unfortunately I can not confirm this with iTunes either... I tested
this with OSX 10.4 and OSX 10.5.

using iTunes and logging in remotely also worked - including audio
playback. I can make a video of this if you don't believe it heh.
