The short answer is yes.  You can manage the links between each broker 
and create hierarchies to your hearts desire.  Performance _is_ an issue 
- especially if you are bandwidth conscious.  You'll need to manage, as 
appropriate, what endpoints/destinations are allowed to be "shared" 
across your infrastructure (between each broker link).

I'm not exactly sure how the master/slave system can accommodate 
horizontal tiers...sorry.
