Hi Jim, How big is your network? Do you see any significant degradation with a network of replicated levelDB brokers? Please see my comment below in red on my original post on the forum.

You can then network those sets of brokers together using networkConnectors. That's what we're planning on deploying. It's what I've been testing for our setup. [ksu] How are you planning on discover the brokers? Via multi-cast auto-discovery, or by specifying URLs statically? The later gets harder to maintain as the the fabric’s membership grows. However, I am not sure if there is any timing issue associated with the auto-discovery of masters, and the auto-discvoery of brokers for the network. > Is this possible?

I've not seen any response to my patch, so while I've got a patched version for myself it's not clear to me whether or not the fix will be accepted by the developers. [ksu] Could you share the patch? Which version of ActiveMQ are you using?
