I think it would hammer home to politicians the power of this technology. Especially if you leveraged technologies like tor and bit-torrent to do the tracking, so that legislation couldn't just shut it down.

Whether we like it or not, privacy is disappearing for citizens. And it's a one way street. If we want our legal system to evolve in a way that accommodates this intelligently, our lawmakers need to be feeling the full impact of the change.

Otherwise we will end up in a place where there's a class of people with no privacy at all, and a class of people who do the surveillance.
