What would be even better, is that we offer a self-hosted version. In an ideal world, I'd open source all of abicollab.net right now, but we need to have an business plan discussion first before we decide to do that:)
Actually, you can create permalinks to a document in any format you like, such as PDF,.docx,.odf, rtf, html, or other formats. As soon as you make an edit, all permalinks will be automatically be updated with the latest document contents, thus removing the need to "export" in a particular format yourself.

The http://abicollab.net website also enables documents to be stored online, allows format conversion on the fly, stores the history of the docs in svn, provides direct links to HTML-ized docs that update as you save them and allows easy sharing of docs amongst friends and groups.
All in all, new competition for Google Docs and Zoho Writer but one that employs a real Word Processor rather than an app in a browser.

In addition to support for annotations (comments) and native SVGs, it comes with powerful, real-time collaboration capabilities that were originally developed for the One Laptop Per Child project. With this release, users can now collaborate with multiple people on the same document at the same time, using all of the rich-text features that AbiWord brings to the table. These features are tightly integrated with a new online web service called AbiCollab.net, which lets you store documents online, allows easy document sharing with your friends, and performs format conversions on the fly.
RTLinuxFree does this. The default scheduler is kinda lame (at least last time I hacked on it), but you can for example replace them with my DMI and EDFI schedulers to get all the fancy features you describe, and more.
