text: is there software out there that will allow 2 users to work on one pc? i feel that most computers are capable of handling that setup -- windows is multiuser, many video cards support two displays, and all pcs can have both a ps/2 and usb keyboards and mice.  it seems the hardware is there and all that is lacking is os support.   you can do this with a local network but at much greater cost and complexity.  wish microsoft would implement such a feature in future os.  more of a must-buy than all the eye candy of vista. best of luck  --- sheer madness , this ! one user trying to close a word file, another user typing on it ... which command is valid !
