The data would indeed need to be presented nicely to the user via the chrome. It is really important that this happen in the chrome, because that is the part the user can trust. So imagine that one develop the cookied mechanism into a WebID cookie somehow. Then one could have the HTTP header return something like Cookie: .... WebID-Cookie: /users/george Where an HTTP GET on /users/george would return a document semantically equivalent to something like the following Turtle ( http://w3.org/TR/Turtle ) <> a foaf:PersonalProfileDocument; foaf:primaryTopic <#me> . <#me> a foaf:Person; foaf:icon <img/smal-pic> ; foaf:homePage <.> . the browser can then fetch this document to give a UI for that site, where of course all the above data is access controlled and only visible to the user with that cookie. As the user changes his profile on his home page, so the icon in his chrome would change too. Now all that http://webid.info/spec/ does is allow the same to be done on a global scale for users that want to be able to link up across web sites. This can in fact increases privacy as I argued in "Liking Linkability" thread http://lists.w3.org/Archives/Public/public-webid/2012Oct/0071.html but ONLY IF Transparency of identity is correctly implemented in the browser.

I thought you wanted a visual indicator somewhere "this site has cookies set". Aza seems to be saying here "you are logged-in to this site as GuyFawkes". These are different statements, and the first has questionnable value.
