Steve,
Suppose, rhetorically, that we were to encrypt every IP packet using IPSEC.
What happens if a box takes your packet and deliver it to the "wrong"
address, for example to an ISP controlled cache? Well, the cache cannot do
anything with it, except drop it to the floor. We are thus faced with a
dilemma: not use IPSEC because it breaks the ISP provided "enhancement," or
tell the ISP to stop this denial of service attack.
