Hey, just curious if there is a plan (or maybe it already exists) to
provide support for interoperability between AMQ versions? I ask,
because I recently started working on GBuild again, which uses AMQ...
I setup a 4.0.1 broker, but my clients were using the 4.1-incubator*
and 4.0.1 broker was puking out CNFE exceptions:

I think I am probably going to just embed a broker in each GBuild
node and use network connectors from the slaves back to the master
node for connectivity so that its easier to use the m2 deps from 4.1-
incubator* to keep things in sync (among other reasons).

But, just wondering if there was a plan for broader interop?
