cg1 - For remote desktop connection, you need 2 seperate monitors. What he's asking is if he can share a monitor between the 2 computers.
Basically, the answer is no. Right now, it's not possible to use a laptop monitor with a desktop pc without spending more money than actually just buying a decent desktop monitor. For your mouse and keyboard though, the Belkin Flip can switch between computers for a monitor, mouse, keyboard, and speakers. It's $50-$60, depending on if you want USB or PS/2 compatibility.
