Is it possible to tap into the VGA output of a (different) computer? The computer in question will be running a driving simulator (which is at full screen). I would like to feed this video to another computer running a program, that I've written, which can detect motorway/freeway lanes and generate an output to steer the vehicle running in the driving simulator.

I did find this: <http://www.synthenv.com/PixelPusher_usb_frame_grabber.aspx>

A Frame grabber that can a VGA input and output it as a USB. Its also compatible with OpenCV (which is what I'm using for computer vision). Any suggestions on how to go about this?
