We created a PoC a while ago showing ETag + browser fingerprinting to replace cookies/client-side storage: http://www.adperium.com/tracking
It works in all major (desktop) browsers, but not in some mobile browsers.
I think the cookie debate (in the EU) is not in the best interest of users: with cookies, the user has full control of the data stored, can easily purge cookies, etc. With user-tagging technology moving server-side, this gets a lot more complicated.
