Thanks for this suggestion.  It forced me to learn a little about PAM.

As I understand it, this would give RT privs to any user who runs
qjackctl.  One thing that wasn't clear to me is what constitutes a
"session".  If they run qjackctl, do the limit changes affect anything
the user does from that point on?  Or is it limited to the qjackctl
process and whatever it runs.

This is pretty neat, but I think one of our goals was to require admin
privs to grant RT privs to users because of the inherent dangers of
handing them out to everybody.  Is this not really a worthwhile goal?
