I still don't get it; why 2 brokers in the same JVM on the same box?

Usually for high performance a broker persists to the local hard
drive; so I don't understand the benefit from having 2 different
brokers writing to 2 different directories (or even different DBs)

You configure the broker names in the activemq.xml. See the brokerName
atttribute in the one that comes with the binary distro
