       talkd - remote user communication server


       Talkd  is the server that notifies a user that somebody else wants to initiate a conversa-
       tion.  It acts a repository of invitations, responding to requests by clients  wishing  to
       rendezvous to hold a conversation.  In normal operation, a client, the caller, initiates a
       rendezvous by sending a CTL_MSG to the server of type LOOK_UP  (see  <protocols/talkd.h>).
       This causes the server to search its invitation tables to check if an invitation currently
       exists for the caller (to speak to the callee specified in the message).   If  the  lookup
       fails,  the  caller  then  sends  an  ANNOUNCE  message causing the server to broadcast an
       announcement on the callee's login ports requesting contact.  When  the	callee	responds,
       the  local  server uses the recorded invitation to respond with the appropriate rendezvous
       address and the caller and callee client programs establish a  stream  connection  through
       which the conversation takes place.
