ah, great, no browser changes! :) i but i have a slight problem seeing
how you can communicate from the WWW browser that's ultimately displaying
the HTML to the perl scripts that generates the HTML, if they are run on
the client side -- i they do, they're the browser for media type
application/x-rcs, aren't they? e.g., when you click on a branch you
want that branch displayed, that means the URL must somehow point back
the perl scripts (they'd have to act as a server as well, then?).

well, this is an implementation detail, and a feature of putting revision
support external to the WWW browser.

great idea that may be acceptable to both camps: use RCS to represent
revision information, but use special HTML tags/attributes in order for
the browser to accurately render revision changes.

still, there's the problem of logically extracting moved blocks between
two revisions; that might be better supported by the HTML editor when the
user moves some HTML, and it would require some special purpose HTML to b=
