That is a great project. I read all details provided here. Actually I was also looking for a similar app which can do the similar work. If I go in details, I read an article today, which is given in end. And in this article there is one app explained which can completely synchronize one Android phone to another. Similarly I want the blueprints of such app, and current project will also help me a lot.
