Update:
I use the trackball and the LED screen sharing feature everyday as my main input device with no problems. So finishing this project is important to me because I really want one of these now.

This project will probably split into two or more projects:

1. The New Device: Driverless Mouse and Keyboard Sharing.
2. My trackball project (here)
3. Other controllers.

Details and further development for the Driverless Mouse and Keyboard Sharing:

Side notes:

The three computer system and my desk will be dismantled, and the project is going on the road with me. Project logs may be slow, please be patient.
