Sure. What I have is a frontend and a backend  with RabbitMQ in between.
The frontend and the backend consist of multiple nodes to spread the
load. However I need to consistently route the traffic from the frontend
to the same node in the backend. Initially the routing key is only known
in the frontend, so I can not have backend nodes binding themselves to
the exchange, as they don't know the key. Hence my custom exchange type,
that binds the queues dynamically.

Cheers,
Levi
