Screen grabbing and real time streaming

I need to grab a portion of the screen and feed it into vvvv in real time (exactly as the jit.desktop node in jitter). Is that possible at all? Any specific node doing this?
any help is VVVVery apreciated!

i got Camtasia to record and output the stream, on vvvv as input for videotexture i can choose the camtasia studio driver, but then nothing appear, it’s completely black.
Anyone had used Camtasia to accomplish this? Attached the patch I’m working on…

if you like to do it by video in i would recommend this driver:

but i would try the ScreenShot node before:
