Actually this is quite old... a contract I was charged with about 5 years ago was not only persistent cookies, but also to determine if the visitor has been to competitor sites recently as well.
It worked beautifully... and technology has progressed quite a bit since then.
If this is implemented correctly, there is really nothing that 99% of your users can do, using existing technology without taking a huge hit to performance.
