It is a question of when you GET the page that the link leads
to.  

The idea is that if there is an un-explained link in page A which
leads to page B, then why not pre-fetch page B and extract its
TITLE which would then be displayed as the link text in page A
where there is a link to page B.

Maybe the best thing to do with this technique is to experiment
with it under the WAI-ERT umbrella.  It may be that it is a
reasonable source of ALT text suggestions for authors.  Or it may
turn out that authors who insert image links without ALT, link to
authors who post pages without TITLE. 

There are options in HTTP where you can get just the top n bytes
of a page, so we don't absolutely have to pre-fetch the whole
page.  But the text of the page is not the bandwidth problem,
anyway.

For Author prompting, if there is a META SUMMARY tag which has
been inserted to make search engine hits format cleanly, that is
golden and the SUMMARY should be used as a clue if the author
of the referring page can't quickly come up with link text.

But simply a tiled over/under display of the "from" and "to"
points of the link (positioned viewframe selected from HTML
document) is what may make the most sense as an aid in authoring.

For authoring, what is critical is to communicate the link [ALT]
text question to the author as an issue of continuity.  Everybody
has had their composition teacher tell them they need to scrub up
their continuity at some time in their life.

Hope this helps.  I haven't reviewed the full context.
