Thanks John! Turned out the main issue was that I was installing this in
OpenStack instances, and forgot about the security group rules. Since
those get enforced in the host, not in the guest, it was invisible to me
- iptables looked fine.

I did add that line to rabbitmq.conf, with Dan Radez's help, in
/usr/lib/python2.7/site-packages/packstack/puppet/templates/amqp.pp in
the rabbitmp class. I still have not had a successful run, but I've been
hitting a different issue each time.

My latest issue was due to using floating IP addresses for the hosts -
mongodb would not bind to that address - so I had to switch to the
internal IP addresses (unfortunately, as I understand those will not
stay the same over time).

After resolving that, I have now hit an issue with Swift ring failing to
rebalance. I have no idea what that means or how to fix it, the
information I have suggests that nuking from orbit and restarting is the
best approach.

Thanks,
Dave.
