Between CastAR and Oculus Rift, it just seems an embarassment of riches, speaking as someone who spent a brief time working in VR in the early 90s.

It seems to me that the Oculus is for immersive environments; CastAR for shared and/or augmented reality.

Adapting Oculus Demos would be awkward because CastAR has the reflective surfaces as limited "portals" into the 3d environment. Although I'd guess the 3d engine work would be easily adaptable.

They have a clip-on to the glasses that convert from AR to VR mode. So you wouldn't need a reflective surface portal as you say. I believe switching between the two headsets would just be a matter of software. I'm wondering if that support exists or is easy to make, or whether there would be difficult challenges to it.

Basically, I'd prefer to buy one system that could be both AR and VR than two separate systems, one for VR and one for AR. So that would make CastAR beat out Oculus Rift unless the Oculus Rift was just so much better or the software was incompatible.
