http://openomy.com/

Openomy is an online file system. You can store files on Openomy and access them from any computer. Openomy organizes files and users via tags (as opposed to folders). You can choose to keep your files guarded by Openomy, or allow certain outside applications (of your choice) to do new and interesting things with your data.
