   In this code, it seems obvious to me that the -k option is not supported
   outside of Kerberos 4 authentication.  Therefore, my questions are:

      1. Is it really true that the -k option is only supported within
	 Kerberos 4 authentication and thus not intended for support
	 within Kerberos 5 authentication?

No.

      2. a. If the answer to #1 is yes, then is there another way in which
	    this functionality is implemented?

Yes.

	 b. If the answer to #1 is no, please elaborate on what it would
	    take to support the -k option for Kerberos 5.

See the telnet in the application in the MIT distribution of the
Kerberos V5 sources; the telnet distributed with Kerberos V5 does
support the -k option.
