Is there an "Ubuntu Studio Controls" application still around? If so, 
that might be the right place to aid with this.

Or possibly one could add some kind of script that would give RT prio to 
the current logged in user (and remove it if the user logs out)? I 
wonder if that is possible, but if so, that might be a useful solution 
for the Live DVD as well.
