There has been a fair number of messages on the kerberos mailing-list that 
suggest using kerberos with ISO standards.  The following is an example.
Would anyone on the ISO discussion list care to comment on this concept?
Please also copy your comments to kerberos@athena.mit.edu.

    Note that the password encoding within FTAM is expressed as

        Password ::= [APPLICATION 17] CHOICE {
            GraphicString,
            OCTET STRING }

    The octet string encoding choice was explicitly placed there for future
    use of better authentication techniques than graphicstring passwords.
    Stick your Kerberos ticket in there, and you've got strong
    authentication, and are completely ISO conformant!
