multiple-monitors

Does anyone know of any software/hardware configuration that will allow you to preview/view the contents multiple monitors on one monitor? Let's pretend:

I have two monitors hooked up to one pc, Monitor A and Monitor B. The monitors are not near each other.
I'd like to be able to preview/see what's displaying on Monitor B on Monitor A

I haven't been able to find much about this, but I imagine it may not currently be possible to access/emulate video output going out of a video port in software.

However, wouldn't it be possible to capture display data generated by the OS kernel or data getting passed down to the display adapter driver?
