[PD] (GEM) Getting the z-buffer value of a pixel in a rendered image

Is there a way in GEM to take a snapshot of a rendered scene (such as 
with pix_snap) and save the z-buffer information, for example saving it 
as an extra channel? (e.g. have the z value saved as the alpha channel)?

I'm interested in getting an image of the scene as it would appear if it 
was captured by a depth sensor like a Kinect...
