Similarly, full `Link` header support would also make it possible to have feed-autodiscovery on non-HTML pages (like images, audio, video, plain text files, etc).

One idea is injecting some temporary content in all pages of a site without changing the actual content. For example in the recent SOPA blackout, server owners could have injected a css file with a simple configuration of their webserver.
