As some others pointed out, you can easily access to a branch of the DOM
tree without touching the rest, pretty much like with Emacs. If you want
to play with that, install Firefox and its "firebug" extension. Within
minute you will be able to live-change parts of your web pages, both the
content and the style.

Emacs could easily use the big-file-in-many-chunks strategy, the
rendering engine would only be a rendering engine, i.e. no direct access
to file content.

Live-editing parts of a big wikipedia article with Firebug is
instantaneous on my good old laptop. The only cascading effect I can
think of is the visual filling, but now emacs does it as well so I'm not
sure it would be worst with a xhtml display engine.
