   	could you tell me why you don't use getaddrinfo(AI_PASSIVE) and obey
   	the result?  by doing so your application will be totally address
   	family independent (no AF_INET6 hardcoded) and will be future-proven
   	(will work with SCTP, DCCP or even IPv8 :-).
   
=> you already know the answer: because I'd like to listen on only a socket.
And this is address family independent (getaddrinfo is not defined for
AF_ISO for instance) and transport protocol independent (it works with
SCTP).

This is my last message about this topic.
