At work i use, x2vnc (there is also a windows version too, win2vnc) so i can use the same mouse+keyboard across my linux, windows xp and mac computers I have in front of me, I just move my mouse to the left or right of my linux screen and I'm instantly in charge of the mac or redmond (which ever way i go :))
