Yesterday Microsoft posted an Office Live Add-in for Microsoft Office at its download site, here. The description of the download says it will add new menu option to Office so you can open and save your office documents directly from Microsoft Office to your Office Live Workspace.
This is probably a pretty good indicator that Office Live Workspace is going to kick of a beta before too long. If you are interested in this it might be worth Pre-Registering if you haven’t already.
