Perhaps the notion of a well known port is a concept whose time has passed. At least for connection oriented protocols, doing away with well known ports might have some good properties for some basic authentication/cookie mechanism as well. Or we could just let HTTP become the transport layer until blocking is done within the content of those messages, but we can just keep building transports on top until some MTU is reached. :-) John
