Sounds good.
For the second monitor idea: I’d say no - Not having 1 to 1 head tracking/movement is a bad idea in terms of motion sickness. - There’s also a lot that happens for VR to be comfortable. (Slightly different image per eye, barrel distortion to counteract lens distortion)
Maybe some sort of ‘Virtual Desktop’ (watching a 2D screen in VR) could be a middle-ground.
Fastest/Easiest way to ship them something would be to use the ‘Start in VR’ project setting and configure the app to dump them straight into the cockpit (Bypass any need to worry about front-end UI)
