[Just a bit of context, some of this conversation happened off list--I'm
trying to start a rabbitmq cluster on some firewalled EC2 instances, and
Emile has been helping me identify all the details about ports and
configuration and all that good stuff.]

We're looking to open fewer ports, not more.* *Is there a minimum we could
do? Would one work, or would it break something else?

Also, we have these ports open to all TCP.  In the spirit of securing our
systems, I guess we could open 4369 only to the IPs of the other machines
in the cluster. Is that a good idea? Can you think of more firewall
restrictions to add?
