The visitor heuristic (UserIP+Browser+Plugins) as identifier as an alternative for cookies is nice for smaller public websites. It will not work properly on sites with higher trafffic from hughe companies. (centralized computer settings, no identifiable IP Adress).
It would be nice to have a switch to turn this off.
