I wrote this lnternet-Draft so that we could explore the ESPv3 support for 
authenticated encryption modes.  CCM is the only unencumbered 
authentication encryption mode that I know about today.  I hear that 
another is under development, but for now, we can work with CCM to 
determine whether ESPv3 really meets its design objectives.
