Re: def'n of "computer network"

Although I hardly oppose the construction of "headerless" cryptographic protocols, they make key management in any sort of a reasonable system a living hell. If you work for an organization maintaining a reasonable number of keys -- say a few hundred at some institution -- you will have to linearly search them to find which one is the right one. What a royal pain. Rapid deployment in ordinary software is, of course, preferable. Perry
