Thinking about the approach I'm using in delicious Feed Enhancer - Auto-Enclosures - using web page URLs to generate the URL for media items embedded in - or linked to from - a page, it strikes me that one way of opening up the page so that it reveals the media items embedded in it would be to use some form of media autodiscovery.
This could work in much the same way as (RSS) feed autodiscovery. That is, a link tag is added to the head of an HTML document that points to the embedded media resource/linked to media resource/associated feed.
An enclosure tag for web pages, in other words...
As well as making it easy to scrape significant embedded media elements from a page, this approach could also be used to help browsers identify and opportunistically prefetch large media items associated with a particular webpage?
