Hi Joe, the main question is do you really need that many clients and can you redesign your system to use smaller number of clients and selectors for example?
as of scaling, the best starting point to scaling the broker is this article http://activemq.apache.org/how-do-i-configure-10s-of-1000s-of-queues-in-a-single-broker-.html and looking into activemq-scalability.xml provided with the ActiveMQ distribution. You may also want to consider creating a network of brokers for this task. As long as restraining number of connections, you can take a look here https://issues.apache.org/activemq/browse/AMQ-1928 for the similar feature. Just that it throws an exception instead of waiting for the connection to be stopped. Finally, you can write a plugin http://activemq.apache.org/developing-plugins.html that will do what you want.
