Cool, so a simple scenario could be:

Cluster A (USA) <------> Cluster B (Europe)

which would allow systems in the USA to publish to Cluster A, and systems
in Europe to publish to Cluster B.

Cluster A then federates its messages to Cluster B, which is where all the
subscribers/consumers live.

So essentially it's a reliable way to allow the USA to publish messages to
RabbitMQ whilst still allowing Europe to subscribe to and consume the

Can it work bi-directionally too? So Europe could federate to the USA too
(for the same exchange)? That way we could potentially do it without the
cluster at each end.
