It's possible, I just don't believe the hardware is available. It would require a VGA input and a splitter between your desktop monitor and the notebook. While the splitters exist, I'm not sure about the VGA input. Try searching Google.com for it.
Ep, glad to see you come back and tidy up...did want to ask a one day favor, I want to enhance my resume , was hoping you could make me administrator for a day, if so, take me right off since I won't be here to do anything, and don't know the slightest about the board, but it would be nice putting "served administrator osnn", if can do, THANKS
