Actually it is possible to do low latency while using X server (for those not on Wayland), but it seems much faster to stream a video of the screen area than to use X protocol directly (which I have often used over SSH in the past to control another desktop system) - Xpra seems much faster to me. I've tried x11vnc too. Xpra is cool. Just my subjective experience, but proper benchmark stats would be cool to see.
