Well, my idea was not that sophisticated but yes, it belongs to the
passive attacks available to exit mixes I generally had in mind (and I
agree that the current domain-based proposal makes it way harder for an
active mix attacker). My example used just one session. And I still
would claim that even this gives an exit mix means to track users during
the 10 minutes (and later if the user happens to get the same exit mix
again within the same browsing session). If this is true do you mean
that it is just not worth the effort or is to difficult to explain to
the user (as it is highly probably that avoiding this kind of tracking
implies breaking some functionality in the web (a kind of tab separation
would be necessary but not sufficient))?
