I was thinking about datacenter/network topology aware dynamic groups as one of the ideas for how a leader would impose structure or how a group would self organize. All nodes could keep statistics, as well as use user defined metadata, and when they are chosen as leader or group leader to figure out group structure to minimize latency considering latency time is based on slowest path to leader.
