Another good approach to "alternatives for text" is to provide valid
keywords -- not just for the entire page, but metadata that applies only
to a particular section as well.  (Note to self:  Recommend this to WAI
PF for XMLGL consideration.)

Using those keywords, an indexed library of graphics, and a reasonably
intelligent keyword-matching algorithm, you could probably get some
good alternative content.  This could be done in-browser, on the
server, or via a proxy.  Note that it's not quite the same as relying
on "text", as the keywords are just a textual -expression- of a
particular idea, and the actual output to the user could be in a
variety of forms, including graphical.

(For fun, imagine if you will a proxy which scans the keywords and/or
content and matches them against an indexed library of background
sounds -- under user control, of course.  This could provide a sense
of "tone" to a page analogous to color choices in visual design.)
