> 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.
