So, sorry I am usually a lurker but I had to chime in on this. I have to disagree with everyone who doesn't think this is an awesome idea. I have been wanting this since it has first been even hinted it way back. I think the modding community will get behind it once the new Oculus hits. There have already been people who have done it with the old ones, and head tracking is available from KerbTrack already.
Really though, the thing that will make it all fit together will be Oculus CV1 with the head tracking, and the Touch controllers. I imagine doing moon landings from the lander can, and leaning forward to see better out the window just how much farther the ground is. I imagine my hands being turned into Kerbal hands sitting in the cockpit, moving the throttle, actually reaching out to touch the buttons on my rasterprop monitors, flicking switches. Imagine being EVA in first person, and the Touch controllers are your RCS control. You could rotate your wrist to get your translation/rotation due to the constellation/accelerometer tracking. To me, that is what is going to give the immersion and make it worth it.
It could be even possible to build your ship entirely in the new Rift using the Touch controllers. All of functions for accurate placement could be there. It would be nearly Ironman-esque. Reach out and place a part, spin it around.
It would be so cool to not only design your own rocket, but then to get to really fly it and do the mission. It would completely enhance pure IVA flight. I think it would add a capability and depth to the game that can't be matched. Anyone who has ever played pure IVA nows how much of a pain it is to keep clicking around just to move the camera. Zoom in, check that screen, zoom out, move camera, zoom in check that gauge...etc. Instead just move your head, lean in to see closer, reach out and touch the button you want.
And there is no reason it should not be even MORE possible with 1.1 with Unity 5s direct support for VR. As I understand it, it can be as simple as a checkbox. The Touch integration would definately take some work. But I'm sure its nothing this community can't handle. Kerbal stuff was down for less than 8 hours and new plans were being organized, and within 48 a new site up, and now its almost like nothing ever happened. So I can't agree that it won't happen or is a dumb idea.
