I think this won't work except when you're lucky (e.g. when the changes
are very minimal). The text-diff is unaware of the HTML structure. This
is where Guy's HTML-diff project for gsoc would help.

To completely replace the HTML in the htmlarea, it would need to go
through the initialization code again, which can be found in
daisy_edit.js, however this code is currently not isolated nor designed
for re-initialization. You're on your own here.
