It could potentially be set up that way if you had all public IP addresses. I
just confirmed at ?DAYJOB that we do not have public IP's and all the traffic
flows through our load balancers and the servers pass a private IP back and forth.

This is why I think EC2 is a bit broken. They gotta be hearing this from the
masses. Hopefully they have a solution forthcoming.
How does your 'A records with multiple IPs' work? You're using your registrar
as a load balancer? I guess you don't have much of a chance to manage
affinity, if you need it at all.
