As I understand it, it's not vnc, but more a kind of x-forward.. performance is great, just like been connected to the nvidia card directly (or close too).. this is not just a POC.. this is actually usable!!..

Regard arch, I don't know.. but isn't it packaged the same way in ubuntu???

Using vnc seems like it would induce some lag or cpu cycles. Whats the
performance like?

Also on a related note, I use Arch, and since libgl gets packaged with with
the nvidia proprietary modules now, I'm guessing I would need to find a way
to install both the open source libgl and the nvidia one? Thanks
