Integrate Google Docs into Microsoft Office

http://www.offisync.com/
Their site says:
OffiSync Supercharges Microsoft Office, enabling users to significantly improve the way they create, collaborate and share their documents by integrating Microsoft Office with Google Docs, and Google Apps.
I haven’t used it yet, but I saw the extra tab inside MS Word when I opened it up.
I liked the image on their site which explains it visually:

*Postscript:  
I have had some problems with Word 2010 Beta and the error message said it had something to to with Offisync.  I'm not sure if that was actually the problem, but I uninstalled it anyway.  Also there are some quirks with formatting not carrying over into the GDocs version of the document and the sync - I think - only workds from the desktop doc to the web and NOT the other way around.
