Multi Touch? (Score 1)

I wonder if 'Multi-Touch' Support can translate easily to 'Multi-mouse'. Not two mice fighting to control one cursor aka windows today, but some extended combination (n mice = n cursors) Modern PC's support multiple screens, many applications but still single inputs. Is there an official reason why an OS can not support two sets of monitor/mouse/keyboard? Limiting each to a screen should be possible. Still no reason why they could not interact too. This would bring a whole new level to extreme programming!
