Scatter With Terrain Displacement

Is it possible to have the scattered objects being affected with the displacement.
For example if I have a plane that I have displaced with vray to a mountain shape, would it be possible for the trees to follow the shape.
I always had this issue when populating trees on mountain with displacement, you get some trees flying or others under the terrain.

Yes, It doesn't work, you don't get the same result at all, plus you don't have the controls like in the displacement.

unfortunately this is not possible to achieve with scattering
as displacement happens during rendering process
and scattering generates geometry before rendering

I kind of figured that, but wouldn't be possible to add this feature in some way.

This is impossible to add by 2 reasons:
1. There is no way to get subdivision data because it is generated at render time.
2. Even if I could get subdivision data it will be huge (micropolygon displacement will generate millons of triangles) and it will use all RAM/CPU time to generate scattered objects...
