And please don't add any more layering violations. It makes implementors life painful and kills any architectual cleaniess in operating systems.
i have long wished for and sometimes needed a way to renumber a host w/o killing or restarting its active tcp flows. this isn't a layering violation. tcp should be able to know about endpoint-renumber events.
Unfortunately this sounds like a good target for people to mess up implementations and introduce huge security issues into TCP stacks. (along the theme of the one which started the recent MD5 discussion) But obviously, implemeted properly that would be very useful. The problem then becomes, how an ISP can signal a renumber. Pete
