Looking for a developer of an application that will enable to use iPhone as an external mouse for a mac and pc. When a user moves his finger on the iPhone the mouse on a mac or pc should move as well with the direction of finger movement.

There are a couple of similar applications available for sale on the Apple AppStore.

What parts of the software should be created:
- iPhone application that will transfer to a computer signals concerning the movement of user's finger. The data should be transferred via wi-fi or/and bluetooth.
- Application on the mac or pc itself that will accept the data from an iPhone and move the cursor of a mouse according to the data received.

We require all of the sourcecodes be available to us upon completing the task.

Our requirements to the project:
- iPhone part of the application should be written in Objective-c
- Mac/PC part of the application should be written in C++ and should be crossplatform (the same project should compile on both Apple and Microsoft systems).
