The folks at ALVR (another vr streaming client/server) are doing something similar, but are open source : https://github.com/alvr-org/alvr

They also achieve very low latency, I didn't follow every single optimization they added but it basically boils down to a few encoding tricks (better image in the center, accept blurriness in the peripheral vision), good network infrastructure, and hardware decoding / encoding being really fast.

Works for me. Streamed Fallout 4 to my quest.

Can confirm, it works pretty well (and much more convenient than wired). Well I was using Virtual Desktop, but SteamLink probably works similarly.

The spherical reprojection is done on the headset itself. That helps a lot.
