I suppose in the future, anything is possible—but I don't see it. You're asking the local device to do Z translations of a 3D scene when all it has is an already-rendered 2D image.

And the local device will just have a 2D image. Even within a single, local PC, multi-GPU rendering is basically dead for video games because no one has been able to get them working reliably. And that is with the full bandwidth and latency of PCIe.
