Ahh, good times. SSH tunnels and FoxyProxy to run X11 applications on remote servers.

You can also simply use `ssh -X`/`ssh -Y` and use your local X/Xwayland server for the remote app. This way you can start remote GUI apps like local ones from your shell.

How is the latency on that?

Fine if you're on the LAN, but for WAN connections you generally want xpra or NX.

Surprisingly good.

I was running emacs on a machine in the cloud on the east coast, tunneling to my X server on my laptop on the west coast. No visible keystroke latency. Only noticeable latencies were copy/paste and initial startup but those were only bad enough to be noticeable, not bad enough to annoy me.
