The programs need to be there for approved users (who have separate user
accounts), and for launching by other things that may need them.  I just
want the controls gone from indicator pop up for the restricted, and
generally clueless, guest users who are likely to click anything they see.

Since 'something else' other than the music player and VLC are sticking
the controls into the popup (apparently 'just because the players exist',
since the programs are not running at all), it's not the player programs
themselves causing the issue.  I want to fix whatever is creating the
popup so it's not adding unwanted things.

Also, removing gmusicplayer and VLC wouldn't cure the pop-up having a
'sound settings' link that exposes *ALL* the sound controls.

I've had older non-xubuntu XFCE machines that offer a simple volume
control as a panel widget that have worked fine for years.  Those also
employ XFCE kiosk mode which blocks 'right clicking' from exposing things
the guest account shouldn't ever even see.  A simple volume control's all
I'm after.
