Changes

** We will implement a read-only storage for the ready-made app to read the data via Device Storage API. For example, Video app can play a video in Dropbox even the file size is larger than internal storage without any app modification.<br/>

** Each user might have more than one storage account, so multi-storage support is an important feature for user to manipulate their storage more flexible.<br/>** Second, offline Support is for using storages even there is no network available (, and we can leverage Cache mechanism to implement this feature.)<br/>** From the perspective of storage provider, Flexible Storage Module is an easy way to install or update the storage plugin for 3rd party storage provider like Dropbox, Box.net, etc.<br/>** Multi Storage support will be handled by Account management. 3rd-party Storage plugin and Virtual Storage Interface are the key components to implement Flexible Storage Module.<br/>

** Read-Write support, just like its literal meaning, files can be read or written. Read-Write feature is our last mile to achieve our final destination, and Sync Mechanism should handle all possible conflict when any file is changed from different clients.<br/>
