It's entirely up to you how you federate your clusters. It's important to understand that what you're federating from the upstream is exchanges. You need to consider whether all the exchanges need federating or not. This is really an application dependent decision.

I have no idea what this means. What kind of load balancing are you think of implementing? Is the question whether the connections federation makes to upstream brokers need to be handled 'specially' if they access the upstream via HAProxy?
