Major Description
In the doc for 'Networks of Brokers', http://activemq.apache.org/networks-of-brokers.html, it says that it is sometimes useful to disable conduitSubscriptions for queues, because this gives you a better load balancing effect when consumers are attached to various points in the broker network. The only trouble is, currently it does not seem practical to disable conduitSubscriptions, because this almost inevitably causes trouble with topics. That is, it can easily happen that topic messages are duplicated, if conduitSubscriptions is set to false.
It seems like it would be better if topic subscriptions where always treated as conduits and the conduitSubscriptions attribute only affected queue subscriptions. That way, you could happily disable conduits for queues while leaving it enabled for topics.
A bit of investigation is probably needed, however, to make sure that there aren't any edge cases where you might actually want to disable conduit subscriptions for topics.
