The 'Do Not Track' proposal is a travesty, because it depends on the participation of the violator. Furthermore, it completely invalidates itself, because the only method of compliance is through tracking! Privacy control needs to be in the hands of the user, before a tracking site is even resolved via DNS. A combination of extensions like RequestPolicy and BetterPrivacy go a long way towards achieving this (but new tracking techniques are always being developed). Browsers need to have some of this functionality built-in, instead of trying to protect the sheep by supporting a protocol developed by wolves.
