No, it is similar to <something> over the INTERNET, because the INTERNET is nothing at all like a serial line, the later generally being nicely contained to a single room. > The goal is to delete classic telnet entirely and make it an > (optional) discipline frontend for nc(1).

If you can do it without adding *any complexity* to nc, fine. Except I know you can't do that, it will add substantial complexity. So this seems like a pointless discussion. nc is already more than complex enough. Probably best to focus on making it more secure, before making it support the stone age.
