You seem to forget that the main problem is not transporting the audio data, but interact with other equipment. And there are only so many protocols to do that. Also you have a lot of real world problems like clock distribution or simply broken implementations (it really doesn't work pointing fingers at the broken end of a signal chain if 'other devices *do* work'). In a studio or broadcast environment, reliability is the main concern. The interfaces you have listed are ancient (MADI is 25 years old!) and there simply was nothing the like available at that time. Tell you what: Assemble a system that is able to distribute 64ch audio data transparently and an AES conforming word clock via ethernet between two nodes using open standards and today's equipment, and we'll see if it is cheaper than a MADI setup. You get bonus points if it runs on Linux. I am not trying to defend MADI, but trying to put things a bit into perspective. The price argument will change things rapidly in the near future. But I'm not sure it does today.
