   Something this smart may be able to take some sort of descriptor 
   file combined with a dvi file and form the basis of a hypertext 
   system. Hmm... idx, toc, and glo files could be integrated 
   nicely. I guess the trick would be flagging portions of the dvi
   file...

There is something very crudely approximating this in DVIWindo.  You can
call DVIWindo from another Windows application.  It remembers the handle of
the Window of that application so it can talk back to it later. When 
started from the other application, DVIWindo can be asked to go to a specified
file, on a specified page.  

You can use \specials to set up identifiable sensitive areas (buttons).
When the user clicks in such an area, a message is passed to the calling
application identifying that area. The calling application could then
conceivably do `hyper-text' like things, such as telling DVIWindo to go to a
different page.

The senstive areas can be invisible, or, more usefully, made apparent to the
user by using \specials for reverse video in text, or for colored text, or
for colored rules, or by having an image there, for example, using an
inserted TIFF image (or EPSF or EPSI).

Still, somebody would have to write the `driving' application that embodies 
the `hyper-text' (or whatever) logic to be used...
