Most people's time spent setting up JACK is because they are on a Linux
distribution that doesn't come configured correctly for using realtime
media applications. On systems that are, running JACK is essentially
trivial unless you insist on using USB audio interfaces which, partly
because of their terrible h/w design and partly because of ALSA's poor
driver support for them (compared to OS X and Windows), tend to be more

this is not a known feature of JACK SVN.

its not in process, and its not strictly a redesign.

wierd that. the pro-audio world seems to love JACK.

i guess you must have missed jack_set_buffer_size(). or perhaps you're
stuck with JACK clients that don't want to handle such things, and JACK
is just being respectful of their limitations. who really knows?

that must be why all the commercial companies i interact with want
windows versions.

JACK has a number of problems, some of them significant. The things
you've spoken about are not among them.
