// ClientID is an abstract identifier that binds together all the communications
// belonging to a single client session, even though those communications may
// arrive from multiple IP addresses or over multiple lower-level connections.
// It plays the same role that an (IP address, port number) tuple plays in a
// net.UDPConn: it's the return address pertaining to a long-lived abstract
// client session. The client attaches its ClientID to each of its
// communications, enabling the server to disambiguate requests among its many
// clients. ClientID implements the net.Addr interface.
