We would heavily prefer a shared-nothing architecture, and so for this reason

I had not considered a network of Master/Slave brokers, would this look, in
a two machine configuration, something like:

MACHINE1:
   MQ-A-PRIMARY
   MQ-B-BACKUP

MACHINE2:
   MQ-A-BACKUP
   MQ-B-PRIMARY

Where backups would be configured as normal and all servers would be
configured as a network of brokers. Clients would have a connection string
like
"failover://(tcp://MQ-A-PRIMARY:PORT,tcp://MQ-B-PRIMARY:PORT,tcp://MQ-A-BACKUP:PORT,tcp://MQ-B-BACKUP:PORT)"

Would this be a minimal HA cluster?

Yes - 4 brokers in 2 master-slave pairs with the broker M/S pairs
store-and-forwarding to each other.


Incidentally, the "topology" section of the site was not necessarily crystal
clear as to what a typical configuration would look like. I would think
something like a list of use-cases, with a diagram of the topology and some
lniks to .conf files for each would be VERY beneficial.

Agreed. We welcome contributions :)

The website is a wiki so anyone can contribute documentation and diagrams..
