»In which multicast is our king
Stuart Cheshire, designer of Zero-Configuration Networking (that's RFC 3927 to you IETF fans out there) quoted Antoine de Saint-Exupéry today with respect to protocol design: "You know that you have finished not when there is nothing left to add to the protocol, but when there is nothing left to take away from the protocol." Saint-Exupéry was an aviator, and I suspect that he was referring specifically to aircraft design when he said that "La perfection est atteinte non quand il ne reste rien à ajouter, mais quand il ne reste rien à enlever." I think the same applies to bicycles!
