You may have heard of the Multi-Pointer Xserver, a modification to the xserver to allow more than one mouse and keyboard.

It sounds very cool, imagine a dual-monitor setup, with two people using one monitor each, while they each have a separate mouse and keyboard. Or for ambidextrous multi-taskers you could do twice as much!
Has anyone tried this on edgy or feisty. There is already a live-CD using dapper.
Cloning the Xserver is probably beyond my reach, although if it is easier than it sounds it might be ok.
So... just tell me anything about it really.
