Microsoft Office Live Workspace - Beta Release Could Be Close
Microsoft Office Live Workspace, a service that lets you upload Office documents and PDFs online, could be nearing a beta release.
That’s quite a possibility because the Office team just made a public release of Office Live connector - an add-in that allows you to download and save Office documents directly from Word, Excel and PowerPoint programs to your online Office Live Workspace account. See screenshot.

When I tried to pre-register with OfficeLive, I got the following message:
This product is not available in your country or region.
We have had an overwhelming response to Office Live Workspace beta and have temporarily reached the limit for pre-registration for your country

In any case, OfficeLive only works with Internet Explorer:-|
