I need to remove my JMS single point of failure (SPF) in my current design.

Scenario:

1000 end-user applications will publish to n topics.  Each end-user
application will be given primary and secondary broker addresses (different
machines).

There are four message brokers running on two machines (2 brokers per
machine, each machine is quad-processor).

There are three backend servers that serve different functions.  Each server
has a corresponding warm-backup server running in case of failure.

If each backend server creates two durable subscribers on two different
brokers on different host machines for each topic, then have I removed my
JMS SPF?  I think I have.  Are there errors in my thinking?

Thanks --- Ted
