Hi Tim - this may not be as fast as maya's bg shader, but you can create
the effect with a couple of nodes in the render tree:
Plug a mixer2 into the ground plane's material surface input
Plug a raytracing>refraction node into mixer base color (set refraction
to 1, keep ior at 1)
Set the mixer color 1 to black (0,0,0)
Plug an illumination>shadow node into the mixer weight1 input
Inspect the shadow node, check rgb "on"
The result is that the ground plane will now transmit everything behind
it and overlay shadows. Hope this helps.
-Dave

That can´t be that complicated...
