No. It doesn't. In order to do this, you would need to have a video capture device and connect the other computer to it. The quality would be very bad though.

Timbuktu, Apple Remote Desktop, and Microsoft Remote Viewer are basicly KVMs over IP and allow you to control systems remotely. They are awesome, infact my company uses them exclusively.
