Is it possible to have 2 keyboards / Mouse connected to the same computer and at the same time control 2 things at once, so you kind of have 2 arrows, and are able to type in one window with one keyboard and in another with the other keyboard? This would be usefull for me as i am running dual monitor, so when my dad wants to use the comp, i can just move to the other desk, turn the monitor around and then its like been on another computer.
