Have you seen AMQP/1.0?

It's not like MAMA is a new ground-breaking technology meant to replace 
the existing messaging solutions.

First, it've been around for some time already.

Second, it's a niche solution to abstract different messaging products 
in the context of stock trading industry. Obviously, with existing 
proprietary software to deal with, it has to define API rather than a 
protocol.

There's an initiative to standardise a protocol for distributed 
messaging, but it'll take some time to make it ready:
