> Currently we have two instances of the "use the local ip inside the same datacenter trick":
> * Ec2MultiRegionSnitch -- which is obviously EC2 specific
> * YamlFileNetworkTopologySnitch -- which is powerful but verbose
> There is no reason that GossipingPropertyFileSnitch could not (optionally) do the same. Attached is a patch that adds a preferLocal (default==false==current-behavior) property to GossipingPropertyFileSnitch and does the IEndpointStateChangeSubscriber reconnect dance. I based it on the other snitches but admit that they still seem fairly magical to me. This could be a new class that extends GossipingPropertyFileSnitch, but I could not think of a name that wasn't absurdly long.
