I believe fingerprinting is like insider trading in that you won't be able to make the stock exchange invulnerable to insider trading with fixes to the software that runs the stock exchange, and you won't be able to find a purely technical fix to make fingerprinting go away. This sort of thing is best left to regulation, that's what we have a legislative and an executive and laws and courts and all that for, after all.
