I don't have a horse in this race, but: > * User asks proprietary web service to fetch content and render it a specific way, which it does That sounds like Google Translate to me, when pasting a URL. Bonus points if instead of pasting a URL directly, it is submitted to one of the Internet Archive-like sites; and then submit that archive URL to Google Translate. That would be download and adaptation (by Google Translate) of the download and adaptation[1] (by Internet Archive) of the original content. [1]: These archive sites usually present the content in a slightly different way. Granted, it's usually just adding stuff around the page, e.g. to let you move around different snapshots, but that's still showing stuff that was originally not there.
