I can't believe I missed this one - an RFC proposing a new Internet Protocol, published on April 1st 2004. RFC3751: Omniscience Protocol defines "a set of requirements for a new protocol to be used by prosecutors to determine a person's intent, thus reducing the need to dilute the historical legal requirement to show intent and by groups such as the MPAA and RIAA to be sure they are dealing with lawbreakers and not 60 year old non computer users." The main purpose of Omniscience Protocol as described is to control copyright infringement although plagiarism by students is also mentioned. The security requirements in section 3 present something of a challenge with current technology, let alone the functionality required in section 2.2 to determine the user's intent.
