Q: What file types are supported for video playback in SkyDrive?

Q: Which of the Office Web Apps currently supports co-authoring? How about the Office 2010 desktop applications supporting co-authoring of those documents stored on SkyDrive?
Currently, only Excel Web App and OneNote Web App supports co-authoring (multiple people editing the same file at the same time).

Co-authoring is also supported in the Word 2010, PowerPoint 2010 and OneNote 2010 (via shared notebooks) desktop applications when you open your Office document from a Windows Live SkyDrive folder.

This does mean that at the moment, only OneNote notebooks supports co-authoring from both the desktop application and the OneNote Web App. The Excel desktop application does not currently support co-authoring of documents stored on SkyDrive.

Co-authoring will arrive for all of the Office Web Apps by the second half of 2010.
