Xpra is pretty nice, though if you look at the details, it's more similar to vnc than it is to X11 forwarding. Compositing each window is done on the server, the image is then compressed (it can use png, jpeg, mpeg, webp, bmp and a lot more) and sent down, displayed as a child window of the xpra client, and composited on the client computer. The wayland equivalent is waypipe, though I am not sure it handles disconnections and graceful link quality as well. That said, I've often had to manually adjust the frame encoding format, to gain pixel-perfect accuracy at the cost of a few seconds of latency on a sloppy connection, for instance.
