I don't recall ever hearing of a Kerberos telnet wrapper, but
it could be worth a look. We did something like that here with
FTP, for the sake of web development tools that use it, and it
seems to have worked out fairly well. You'd have to know something
about the telnet protocol and how Kerberos fits in, which I guess
you could get from the MIT source.
