Can I use it to e.g. play games on another device, like a PS4?

I thought the PS VR headset would be perfect for this. Unfortunately it requires to be connected by wires which is frustrating. Something like this, but tailored to PS4 would be awesome.

The latencies involved would make you barf in matter of minutes. Streaming over wired ethernet is already barely adequate for action games and VR requires significantly lower latency to feel good.
