Holographic Remoting to multiple HoloLens

[cpollok]

Hi,
I am looking for a way to remotely render high-poly meshes to multiple HoloLenses at once. So the setup would be a single Unity application connected to one or more HoloLens using the Remote Player app (or something custom). Is this possible with the tools provided by the MRTK? Or is there a way to build it myself with the C++ backbone maybe?
I am aware of Azure Remote Rendering, but would prefer something that can be deployed entirely "offline" in a local-only network.
