My audio interface is a Linux computer with FPGAs inside (that actually get field-programmed), with two gigabit Ethernet jacks that each talk to different parts of the machine.

But I don't think anyone here would care about that. It's not such an unusual arrangement. I guess it's kind of impressive to use it on my desk at home, but in pro audio world it's actually kind of mundane.

Maybe I'll write about it more after I get the gumption to gain a root shell on it (or brick it, whichever comes first). I think you guys might find that part more interesting. :)
