I read a lot about new SkyDrive syncing features (syncing of documents, pictures...) coming with Mango. But will this functionality be available to developers or is it limited to applications by Microsoft?
I think this would be great but I didn't find any information on it.
With the current release of the SDK, SkyDrive functionality is not available to third-party developers. As a matter of fact, there is no official public SkyDrive API. There is the unofficial SkyDrive .NET API Client, but since it is not supported by Microsoft, it will be a bit risky to use it in an app that is outside the "just for fun" zone.
More recently there has been an official API released but it is nothing but Javascript libraries. You have to create a browser instance and manipulate that.
Also it's limited to fiddling with photos and documents. If you want to use SkyDrive as a cloud filesystem the a better option is http://cerulean.codeplex.com/documentation
