I think people rightfully expect that they can use their browser's 
privacy settings to clear collected data, be it in cookies, in HTML5 
local storage, in Silverlight Local Storage, or in Flash Client Side 

To make this happen, an API is needed so that UAs can manage the date.

A proposal for that API has been made several months ago, see 
<https://wiki.mozilla.org/Plugins:ClearPrivacyData>, but unfortunately 
*both* UA implementers and plugin implementers are very very very slow 
in making this happen.

Just saying.
