open office collaboration

Hi, I've been collaborating with a bunch of people on an opensource book
for a while now, and I've been considering my ideal application for the
process.  I'm wondering if such a thing exists or if anybody would be
interested in creating it.

It will be used primarily by non-technical people, and thus DocBook and
tex, even html, is *way* to complicated.  I've tried to get people to
learn these thing, but for non-technical people the task is quite
daunting, and the result is, if the projects depends on these tools it
FAILS.  The proper solution is to let people word process like they are
used to word processing, in a word processor like OpenOffice Writer.

The problem with OpenOffice Writer is integrating remote revision
control, similar to cvs or subversion.  Idealy there would be a plugin
for open office which creates an extra menu.  When you open a document
that is under revision control, the menu appears, and under the menu are
the standard items, such as, update and commit.  The location of the
repository is saved in the document.  This makes contributing to the
project as easy as downloading an OpenOffice Writer document from the
web, opening it, editing and selecting commit from the drop down menu
(presumably they would need to enter a username and password as well).

Then of course we would need tools for diffing and dealing with
conflicts.  Some of those things already partially exist in OpenOffice
with the local revision control that is built in.  Perhaps those tools
could be extended.

I believe that a really easy to use tool along these lines would
revolutionize book writing, and writing in general, in the way that open
source software development has revolutionized software development.
I've looked far and wide from something like this, but thus far have
been unable to find anything.

Does anybody like this idea.  Does it make sense?  Should I describe
what I'm thinking about it more detail?
