There are metadata dicitionaries around that describe words in terms of
subclasses - eagle is a subclass of birds of prey, which is a subclass of
birds, etc.

These things are all in RDF, and should therefore be able to have a
URI. Which would enable us to use RDF to link keywords, meanings, and
illustrations.

Which means we could build tools to add this kind of stuff. (Kynn's magic
dream tool...)

  Some more brainstorming:
  
  SMIL already has an abstract attribute for some elements. Maybe that could
  be one way of adding information of major components of content as well as
  the whole page. Short simple text could help also users with small screen
  devices.
  
  If I have interpreted the demands right, the TTS should work with these
  alternative attributes (If they don't has anyone told the TTS developers
  that?) or there should be also an audio version of them. Then similar info
  should be also presented with images. Or maybe the abstract should always
  contain a clarifying image?
  
  Then it would be nice also to have a simple explanation of the navigational
  structure of the site that could be attached to each page. This could help
  many other users too.
