Yes, you can run multiple brokers on a single system. You just need to be mindful of what ports you listen on (via the activemq.xml), and when you are sending messages to the correct ports for each instance.
There is going to be a performance hit of using two servers instead of one, if the system is really busy. If its not, you probably won't notice any major problems. I like running multiple brokers for testing different versions of ActiveMQ or ServiceMix on the same box. As for a production setup, I don't see a benefit to running multiple instances on the same server in the majority of cases-- in fact, I think it creates more administrative and support headaches. I do like the model of running a second instance to take over in the event that the first instance fails, but for just processing messages through queues and topics, one per server is usually fine for most folks-- especially if you have a second server that is part of a cluster of brokers.
