Bad news for Doubleclick et. al., that is unless it's just /.ers using the features! This will get real interesting if lusers' using it with sites that do not post P3P policies (and thereby blocking sites from setting cookies, for example) creates any kind of unrest/discussion about the exchange of marketing data for content and functionality."
One thing no one writing about IE6 seems to note: Microsoft has carefully arranged their MSN cookie setting technique to avoid being blocked by their own browser - they bounce people through msn.com to log in to any Microsoft property, so it's always a "first-party" cookie being sent/placed.
