It seemed an interesting anecdote, but in a more recent post on network neutrality he referenced the TCP encryption proposals again (http://www.reed.com/blog-dpr/?p=85 http://www.reed.com/blog-dpr/?p=85): "In the early days of the Internet design, my officemate at MIT, Steven T. Kent, who is now far more well known as one of the premier experts on secure and trustworthy systems, described how the Internet design could in fact, be designed so that all of the bits delivered from source to destination were encrypted with keys unknown to the intermediate nodes, and we jointly proposed that this be strongly promoted for all users of the Internet. While this proposal was not accepted, because encryption was thought to be too expensive to require for every use, the protocol design of TCP and all other standard protocols have carefully preserved the distinctions needed so that end-to-end encryption can be used. That forces the design to not depend in any way on the content, since encryption means that no one other than the source or destination can possibly understand the meaning of the bits, so the network must be able to do perfectly correct job without knowing same."
