[rabbitmq-discuss] forwarding between vHosts

Hmm - shovels are best for mostly static setups currently...

I experimented as well using federation awhile back, and that is
dynamically configurable by setting policies using the mgt api.

It worked, but at the time federation was new, and I found shovels to be
rugged and suitable for my use case. In our next internal release I think I
will start deploying some federated links however.

So I would try federation if you really need to architect this way.

Good luck!
