There is someone working on an default Debian RT kernel, but isn't very
easy to get that into Debian, but they are open for it.
I think most of what I've read is just another call (as far as Debian
derivatives are concerned), to join the Debian Multimedia Team and help
maintaining some packages.
It's the best thing you can do if we want to enjoy up to date packages.
But unfortunately most of people here are so proud that they can build
packages their own, that they never thought about the idea that building
for others too in an official way would not only help themselves, but
also others and Linux audio in general...
When more people join, the quality will be improved, and in the end less
time will be wasted for tweaking the system instead of making music.
