There is already an IETF draft standard which handles (3), is designed
to allow (2), although there isn't a spec yet, and there are already
application layers out there for a few common protocols (FTP is the
only one publically available right now, as far as I know).  If you're
doing an internet security protocol and you're not considering GSSAPI,
I'm curious why.  If you don't know what it is, take a look at RFC's
1508 and 1509.  There's also an internet-draft spec for a krb5
mechanism, for which an implementation is freely available as a part
of the MIT kerberos 5 release.

I speculate that any protocol at these layers (above IP) which ignores
GSSAPI is likely to be looked upon poorly by the IETF.
