This is certainly true. Someone should really patch the distribution protocol to prioritise heartbeats, but that's a different story....

That's worth considering, although you might be able to work around chatty comms by batching. But if you really think you'll saturate the network then implementing a solution over AMQP might actually be less effort. Let us know how you get on please! :)
