Re[2]: IPSEC document reading party!



     ESP tunneling without encryption cannot be substituted with IP-in-IP 
     tunneling.  It provides authentication and integrity services to the 
     encapsulated packet.  Note that this is different from AH which will 
     cover the outer IP headers and options also.

He's right. If a policy calls for tunneling, the mechanisms should be 
IP-in-IP encapsulation, plain and simple. In other words, it's not that
ESP should be used with no encryption; it's that ESP should not be used at all!
