Markoff writes in the NY Times about a proposal called eDNA which would "reconfigure" the Internet to forbid anonymous usage of certain parts.
http://www.nytimes.com/2002/11/22/politics/22TRAC.html The scheme was explored by DARPA a few months ago, which gave a contract to SRI to look into it. SRI convened a panel that included Matt Blaze, Whit Diffie, Roger Needham and Marc Rotenberg (of EPIC). These guys hated the idea, but the SRI contact, one Victoria Stavridou, refused to allow Blaze to write up the consensus once it became clear that he was going to shred the proposal. The commmitee members exchanged furious emails, full of personal attacks, complaining that Stavridou was hijacking the report. But she persisted, briefing DARPA orally and refusing to include Blaze and the others in the teleconference as had been planned. Despite Stavridou's attempt to spin the results, DARPA currently says it has no intention of pursuing eDNA. SRI says that it concluded "that the costs and risks would outweigh any benefit."
