> For xeyes that works. It is absolutely an inferior and chatty protocol for any other application though, like try to watch a youtube video in chrome through it.

I used run and use diskless SparcStation 5s with remote X on 10BASE2 network with the binaries running on Sun E3500s: it worked well enough for non-video web sites running Netscape 3.x. Also Matlab, Octave, Emacs, Vi(m), etc.

I've used it to run backup application GUIs when I was still on DSL (<25Mbps) displaying at home many years ago, and it worked well then. I now have >100Mbps fibre at home, so doubt that bandwidth (or even latency) is worse.
