well, yes. Wasn't that actually thew question.

Indeed - not only for realtime composers (whatever that might be :-)

Errm, sorry, but a _lot_ do. JackLab (http://jacklab.net/), 
64studio (http://www.64studio.com), UbuntuStudio (http://ubuntustudio.org/),
even our (Freiburg University of Music) homegrown Frankenbuntu distro does it.
There are well-supported realtime/low-latency kernels for (at least) Fedora, SuSE,
Ubuntu and SlackWare available. So it's mostly about integration and _that_ is where
distributions are important.

Many? Which hasn't?

This sentence no grammar. :-) 
But ALSA actually is at 1.0.16 - so we are in release 16 (!) after the
first official stable release. The AutoCAD equivalent would probably be 
Alsa20, or maybe you prefer ALSA2009. Don't be fooled by conservative 
software versioning.

What? What "pro" is seriously using OSS? And who is discussing ALSA vs.
OSS. "Realtime Composing" with OSS.  

There are "issues" in the Linux sound world but they are mostly a
reasult of conflicting interests between us sound users and the (often
paid) kernel developers whose main goal often is disk/IO throughput and 
fair process scheduling. Nothing to blame ALSA (or OSS) for.

So, what do you want to say?

In my very personal experience ALSA is much more stable than jack, but
that's probably hard to gerneralize.

Yes, but, short of dwelling in fanboy contry, could you elaborate on
where PlanetCCRMA is different/better than the "other" Media-centered
