Actually, I'm not sure that GSSAPI will let us do this. A  
GSS_C_NT_HOSTBASED_SERVICE is defined as being "service@hostname",  
with no provision for specifying a realm.
We could define the acceptor identity as a GSS_KRB5_NT_PRINCIPAL_NAME,  
but that completely ties us to using Kerberos as the GSSAPI mechanism.  
It's not clear to me whether a name defined using one OID can be  
portably used by an endpoint expecting a different OID.
