I like your Idea! That would be the ideal modular
platform.
But if we're going the ethernet route why not Ravenna? It's open standard
I think.
Wouldn't there be a possibility to implement DSP or even Jack in Ravenna?
Consoles from Lawo are Linux based and use Ravenna.
Just some quick thoughts.
I just remembered that we had a discussion about Ravenna here before, I
think the conclusion was that it's not that simple...
