// 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.
