-//  A "peer" is a client/server listening on a TCP port that

-//  A "node" is a client/server listening on a UDP port implementing

-//   The DHT is composed of nodes and stores the location of peers.
-//   BitTorrent clients include a DHT node, which is used to contact other nodes
-//   in the DHT to get the location of peers to

-//   Standard use involves creating a Server, and calling Announce on it with
