I agree with your comment.

I'm coming at this exact problem from the opposite direction, making a Markdown-based static-publishing CMS intended for corporate use (aimed at official documentation, standard operating procedures, handbooks, etc) and weening people who are used to it away from Word is the most difficult part of the entire process.

On the other hand, Word falls short when it comes to a large number of related documents, with inconsistent styling, flakey 'hyperlinks', ridiculous attachments and lack of good version control (something Simul appears to be tackling).

There's plenty of room for innovation in this area and props to the OP for actually tackling the harder challenge head on. My fear in trying to sell this to businesses would be that letting their confidential docs leave their network is going to be a hurdle. A self-hosted version would definitely be onto a winner, and anything that's not Sharepoint is a good thing.
