protocol Warp-zillion Opus-to-Opus. Fidonet's

session layer protocol. Although it mentions Opus (a

specific BBS from the 1980s), WaZOO is the session protocol

used for the Fidonet network. Because WaZOO is much more

efficient than other mechanisms (e.g., FTP), it is sometimes

used for automated or batch communications in other parts of

the Internet.
