I think at this point all/most other important audio oriented distros or
add-ons have realtime kernels (64Studio, Ubuntu Studio, Gentoo's pro
audio overlay, Jacklab on SuSE, etc, etc).

I'm not so sure about this.
I think the winner is: ALSA

OSS has been deprecated. Some people bring it up in the lists every once
in a while, the discussion flares up for a while and then dies. 

Obviously ALSA has its share of problems but some people seem to be
forgetting the problems with OSS that made it possible/necessary for
ALSA to exist. 

To me it looks like something like PulseAudio will become the "standard
interface" for non-critical audio apps on the desktop, Jack will remain
the pro api and ALSA will just be what talks to the hardware.
