A user's chatterbot participates in a chat session with other users and the other
users' chatterbots. The originator of an incoming instant message is identified
to such a degree that a buddy on a buddy list is able to determine that the instant
message was sent by a user's chatterbot (e.g., "Jackie's chatterbot"), and not
the user ("Jackie"). The chatterbots can communicate with other chatterbots while
the chatterbots' users listen to the chatterbots converse. The chatterbots may
respond to messages originated by other chatterbots' messages and buddies' (users') messages.
