Some have requested the ability to use PSMoveService in SteamVR without having to use VRidge. See google group discussion "Is it possible to send HMD position to SteamVR without VRidge software?" .

There are two flavors of this request:

1. Use a 3rd psmove controller for head tracking and render the HMD view to a window like the NullDriver Sample that Valve includes with their OpenVR sdk. This is useful for mobile phone users that want to use Moonlight Game Streaming
2. Use a 3rd psmove controller or bulb for head tracking on HMDs that don't support head tracking (like the Deepoon E2 HMD). I assume this approach also would have an approach similar to the NullDriver sample. What is less clear is how the orientation data should work in this approach since you'll have better orientation state from the HMD then you would from a PSMoveController attached to the head.

In either case, we're going to want to implement something similar to the CSampleDeviceDriver class from the NullDriver sample.
