The app detects the headset and the head tracking works. I can move around an empty scene with WASD mode. I can't see any of the UI in the headset so have to look at the mirror image on the monitor to interact. You're probably going to need a floating UI in front of the camera. When I add a character to a scene placement is done with head tracking; I just look at where I want the character to go. However, once the character is placed their skeletal gizmo is still bound to the head tracking position and separates from their body. I've tried loading several poses from the cloud but the app will either crash during load or shortly after the scene loads. They work fine in normal mode without the headset. Also, I was very big due to the IPD. This can be changed in the Oculus Config utility but you'll probably want a slider to change the IPD in the app so people can change from feeling like giants or pixies.
