Cerulean allows WP7 developers to use SkyDrive as a cloud based filesystem.
Cerulean, on the other hand, is implemented in pure C# and does nothing else. Better yet, the same code can be used from a desktop application, providing a shared filesystem to a desktop application and its WP7 counterpart. While you could certainly
do something with web services, SkyDrive as a cloud service gives you effectively unlimited scalability at no outlay.
I need feedback, on the API, on future features and on documentation. Please don't hesitate to start or participate in discussions.
