Eric commented on AMQ-3077:
---------------------------

What is the simplest way to simulate a complex network of brokers situation in 
a small test ? (one JVM that launches X embedded brokers with one transport 
connector and the corresponding multicast network connector ?)

Is there an existing JUnit test that I can use as an initial pattern ?
