Sounds exactly like my experience trying to get netjack working.  I used
the guide on http://trac.jackaudio.org/wiki/WalkThrough/User/NetJack
and got network MIDI and audio connections on the 'master,' but when I
try to run qjackctl on the slave to connect anything, it fails.  I get
the net xrun reports, and there is about 500Kbs traffic between machines
each way over my network, so SOMETHING is happening.  I think if I could
get MIDI and audio connected on my salve, it would work, but neither
qjackctl nor patchage will let me patch to network MIDI or audio ports
on the slave machine.

I've given up for a while.  I asked about the same question as you in a
couple of different forums, and got no response at all.  Either nobody
is trying to do this, or nobody has succeeded.


Check out the website I've been cobbling together.  It will never be done, but it's a start: 

My blog, with commentary on a variety of things, including audio, mixing, equipment, etc, is at:

Staat heißt das kälteste aller kalten Ungeheuer.  Kalt lügt es auch;
und diese Lüge kriecht aus seinem Munde: 'Ich, der Staat, bin das Volk.'
