+// AliveDelegate is used to involve a client in processing
+// a node "alive" message. When a node joins, either through
+// a UDP gossip or TCP push/pull, we update the state of
+// that node via an alive message. This can be used to filter
+// a node out and prevent it from being considered a peer
+// using application specific logic.
+type AliveDelegate interface {
+	// NotifyMerge is invoked when a merge could take place.
+	// Provides a list of the nodes known by the peer. If
+	// the return value is non-nil, the merge is canceled.
