Rudder has a central configuration (via etcd); Weave communicates network changes across all nodes by itself - as long as each new node knows how to contact at least one other node, it will learn of all other nodes and connect to as many as it can. Also Rudder is Layer 3 and Weave is Layer 2 and Weave can encrypt traffic.
