I have built a system that may help (Score 1)

The ICE project is a free software system that uses Subversion to manage document versions, and provides a little web server written in Python that watches a working copy for you. If you use a simple generic template it will also make nice XHTML versions of your documents. You can use Word or OpenOffice.org Writer to edit.

Also makes PDF versions of individual documents, and you can use OpenOffice.org master documents to make book-length PDFs (even from Word files, with some caveats).
