We are using Thrift--very similar to GPB--and RabbitMQ together with
great success. We are using them as entirely separate message
encoding vs. distribution systems, but other people are using them
with tighter integration (e.g. the txAMQP project from FluidInfo,
which I have not tried).

There is a similar situation with Thrift, and I agree that either
would make a poor standard if that were a goal of the AMQP WG.
