As I understand it, the bind/connect choice has nothing to do with the
direction of messages, but
rather which endpoint has a TCP socket that is listening on a port
(the "server" in traditional language) for incoming connections
and which makes a TCP connection (the "client").  That is,
bind/connect refers to the TCP-level actions of bind/connect,
not message direction.
