A very interesting idea!  In the database, tag each line with which version
number in which it originally appeared.  Then a display similar to (but
hopefully far less cluttered than) the 'annotated' source view produced by
the SF CVS  browser could then be produced.  (I.e. "recent" additions or 
changes could be highlighted, and perhaps annotated with the author's name.)
(My guess is that deleted text would not be shown in this display.)

An example of SF CVS 'annotated' source can be found at:
  http://cvs.sourceforge.net/cgi-bin/cvsweb.cgi/phpwiki/lib/editpage.php?annota
te=1.15&cvsroot=phpwiki

Another, simpler, option which has been in the back of my head for a while
now, is just to fix things so that the diff output gets transform.php'ed.
Then one can create a "unified diff" (with infinite context) which will be
the transformed page with changes since the last version highlit.
(One VersionHistory is added, changes since any particular archived version,
could be highlit.)

In other news:

Arno: I greatly appreciate your  comments in the JeffsDatabaseAPI
pages of the PhpWiki.  I've responded to most of your points/questions,
and would be interested to know if you've been swayed at all.

Steve & Others: I look forward to your comments as well.  There's no huge
rush, but it's clear that a fair amount of back-and-forth (and 
around-and-around)
dialog will be needed before any kind of consensus can be reached.  So it
would be good to at least "check-in" with your initial reactions/thoughts
fairly soon.

Also, feel free to suggest alternate database API's (possibly completely
different) (or based more closely on the current API) if that's what you
think we should be considering.



Also, I'm happy to report that Sandra (my wife), Lucy (my dog) and I (along
with most of the rest of Seattle) seem to have survived yesterday's rather
large earthquake in fine shape.
