I've been waiting for it and now it's available more broadly - a way to share files in the could...take a look at SkyDrive. I can see a science project utilizing Spaces, SkyDrive, Astoria, etc to put all the pieces together to make it work...
- An upgraded look and feel — new graphics to go along with your new features!
- "Also on SkyDrive" — easily get back to the SkyDrives you’ve recently visited
- Thumbnail images — we heard you loud and clear, and now you can see thumbnails of your image files
- Drag and drop your files — sick of our five-at-a-time upload limit? Drag and drop your files right onto your SkyDrive
- Embed your stuff anywhere — with just a few clicks, post your files and folders anywhere you can post html
