I don't think that this would make sense?  From my understanding, SSH, 
SSL, and probably Kerberos use much shorter keys than PGP-style keys 
due to the real-time nature of the transaction.  It is not 
computationally feasible to encrypt and decrypt data in real-time with 
a 1024-bit or higher key.  (Also, I believe that Kerberos uses a 
different type of key system.)

Of course, I suppose that it could be handled like IPSEC.  In other 
words, use the extreme key-pair to validate the user at each end and 
encrypt the "lesser" key (which may be randomly generated) to send 
across for real-time communication.  As far as I know, however, SSL is 
already considered secure for some time to come.
