All brokers in a master/slave cluster receive the message; only the
master dispatches it to consumers.

Then messages are stored and forwarded to other master/slave clusters
as they pass along the network-of-brokers (if there are consumers
available on other master/slave clusters).

I still think you're missing something. The broker just dispatches
messages to consumers. Consumer are the things which would parse the
message and do something with it. To a broker; a message is a just a
blob of data to be routed around a network - the Consumer is the thing
which actually does something with it.
