This is from 2015. We're almost into 2017.

- A 4k frame is 3.2 x as much data as the 2160x1200 frame.

- In this case, compression was achieved at 60fps using H265.

- The same spec of equipment should in principle be capable of achieving 60fps * 3.2 = 192fps. That's 5ms latency due to compression.

- Add in the simplicity of many VR scenes - think RecRoom, Windlands... should be fairly easy to compress.

- Audio can be compressed in parallel

"Not possible"?

I disagree, "more than possible two years ago"

Let's look at some real live x265 benchmarks, because you skipped the part where they did it on a beefy dual socket server. Let's take: http://x265.ru/en/x265-hd-benchmark, that benchmark is 1080P, let's assume you're correct with your simplicity and it might be closer to reality.

The fastest listed system there does a blazing 33fps (well that's a broadwell, the 2015 dual socket server is probably atleast the xeon equivalent of it).

And we haven't even looked at the image quality/compression artifacts.

I disagree with your assessment.

Rivvr is apparently a spinoff of Sixa, the appropriate techcrunch article https://techcrunch.com/2016/12/09/sixa-secures-3-5m-as-it-la... repeats the 11ms latency. Maybe it's the same technology? The comments to the techchrunch article do not sound convincing either.
