  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,

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
:/

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