What about something like writely (Score 1)

I am not sure how large your organization is or how comfortable they would feel putting documents on a site like writely.com, but I started using it for similar reasons as you mentioned. I had a large research project which needed the input of multiple other people. As the main researcher I wanted the ability to see who had made changes to the document and basically i wanted revision control which word just wasn't offering. I also wanted the advantages of a word processor. I looked into using latex and svn but I knew that the others in the group weren't computer literate enough to take the time to learn how to use either of these programs.
