Carlos,
for audio over Eth/wireless on ARM I suggest you to give a read to my
recent papers at:
http://a3lab.dii.univpm.it/research/wemust
Those didn't involve Fons' zita-[nj|jn]bridge, which has recently been
released and I will probably use in next refinements of the research
outcome, being tiny and functional.
So far my experience with ARM cores is that you must be careful with Jack.
Old platforms such as Xscale will require you effort for compiling and
working fine. And btw I suggest you to go directly with 2.6 kernel for
real-time audio. Also, I expect it to be tight as a platform for running
Jack (how much memory do you have?) especially at low period sizes (the CPU
risks to be overwhelmed with interrupts).
Definetely Jack has a lot of features that are important even for this
simple task but I'm wondering if there is any gain in embedding only those
needed in a library and use it instead of the whole JACK.
BTW: a nice paper you may want to read:
Reuter, "Case Study: Building an Out Of The Box Raspberry Pi Modular
Synthesizer", LAC 2014

Thanks so much for the info, Leonardo. I'll check it ASAP,

In practice that is not very likely to happen,

I've thought about a similar idea sometime in the past: A distributed

network with thin clients/raspberrys for a home studio or distributed via
some network. I'd be interested in following whatever progress you make.
About that of "distributed band" I red a little about programs to jam via
internet: Netjack, Ninjam, Midikit.

thanks for the answer, I was expecting this, but hadn't measures the
difference between the jack client and alsa driver.
So now it looks like I need to learn how to cross compile jack for
various
ARM devices to have it on the lightweight clients
:/
Rapha?l
