I see your point.

But if I may - using realtime groups for JACK is pretty much standard 
practice in the Linux audio community for Fedora and similar 
distributions. Spend some time on the LAU (Linux Audio Users) mailing 
list, actually go ahead and install and test jackd, qjackctl, a couple 
synths and a sequencer and you'll see what I mean.

I'm not saying it's the best solution. I'm just saying this has been 
used for a long time and there were no riots in the LAU community over 
the real or perceived issues of this method.

Also, allowing any local user realtime privileges may open up other 
problems. Debian has a special user group (the "audio" group) for such 
things. The examples may probably continue.

I think the problem that LAU is facing is that the things that they do 
are not widely known and understood. _That_ is the biggest hurdle in 
integrating advanced audio features in mainstream distributions.
