hint xpra is not necessarily needed if x11 forwarding is sufficient, but xpra might give better performance.
“Xpra is a tool which allows you to run X programs — usually on a remote host — and then direct their display to your local machine, disconnect from these programs, and reconnect from
the same or another machine, all without losing any state. It differs from standard X forwarding in that it allows disconnection and reconnection without disrupting the forwarded
application; it differs from VNC and similar remote display technologies in that xpra is rootless: i.e., applications forwarded by xpra appear on your desktop as normal windows managed
by your window manager, rather than being all “trapped in a box together”. Xpra also uses a custom protocol that is self-tuning and relatively latency-insensitive, and thus is usable
over network connections that are too slow or unreliable for standard X forwarding. Xpra can also be used to shadow an existing X11 display.”
By default the Xpra server announces available sessions (username and display number) via mDNS to the local network. Use mdns=no to disable it.
is a pretty cool “run my gui app on server but display window locally” x11 window forwarding tool.

#OMG! It even allows file upload into the user’s home directory!
holy cow 🙂
it also tries to implement remote-print… meaning: if you open a document on the server, it shall allow you to print locally. (untested)
