Using your phone as a remote control for your Ubuntu computer, via Bluetooth

I literally mean that.

The idea popped in my head a few days ago and i thought it would be quite interesting to see how doable it was.

The hardware used is a Dikom (Broadcom) Usb bluetooth dongle, a Nokia E61i ( Symbian S60 3rd ) and tested on a Dell Inspiron C521 and a PackardBell Easynote R ( both on Hardy Heron 8.04).
It is also assumed that the dongle is connected and the computer can use bluetooth normally.

So looking around for projects that had already done this, i came across three main ones.
