Why not an open API for that matter? What if I want to use my Virtuality HMD, hacked PowerGlove and surplus Ascension Flock-of-Birds rig to drop into a VR world? Why shouldn't I be able to do that if I have the equipment and skills to get it to work?

BTW - I actually do own all of that equipment (collecting older VR gear is a side hobby of mine).

An open API will allow for any VR gear manufacturer to participate.

Think about it this way - what if in the beginning, Facebook only supported Dell branded PCs - or more realistically, only Mozilla on Linux - back when they started? Do you think they'd have been as successful? No way to know, of course, but only supporting one (or a few) manufacturer's devices doesn't seem like the best way forward for quick market saturation.

Whereas an open api would allow for far more people to get into the game; and if things started to take off, you would also see new independents spring up to sell lower cost HMDs, VR rigs, tracking systems, etc as demand heated up.
