Security : Encrypted communication between doozerd instances

[pythonmobile]

If I want to run doozerd on 3 machines, how do i make sure: No one can access them except those machines (probably just iptables? Password support?). Also, I want the communication between the doozerd's to be over ssl. Can this be done, and if yes, how?

I think the "solution" to this, at this stage, is to use etcd.
