Instead of updating failoverMap on every communication we will be doing activelly when server's view (failoverMap and connectionDelegate) has changed. We will have a static list somewhere on the client, and update that list when new nodes are joining the cluster. I will have to think of something, as right now I don't have many details about how this will be implemented.
