Maybe they are talking about using the HTML AppCache/manifest and a script or something that downloads all of the resources in the manifest and background-preloads them in the Google/Facebook/Twitter etc. page/app. Maybe you don't need a script, just a frame. Maybe a special 'article.html' resource or something that is not allowed to have ads/popups/JS etc.

As long as they don't limit that to certain favored organizations.
