I'm pretty sure it can be mapped to different messaging technologies
(there's a zmq driver). I could see myself experimenting on a Zaqar
driver for oslo.messaging in the future.

What I meant is that oslo.messaging is an rpc library and it depends on
few very specific message delivery patterns that are somehow tight/based
on AMQP semantics. Implementing Zaqar's API in oslo.messaging would be
like trying to add an AMQP driver to Zaqar.

Probably "highly tight to AMQP" wasn't the best way to express this,
sorry about that.
