Per Wayland FAQ: Is Wayland network transparent / does it support remote rendering? No, that is outside the scope of Wayland. <snip>
It is also possible to put a remoting protocol into a wayland compositor, either a standalone remoting compositor or as a part of a full desktop compositor. This will let us forward native Wayland applications. The standalone compositor could let you log into a server and run an application back on your desktop. Building the fowarding into the desktop compositor, could let you export or share a window on the fly with a remote wayland compositor, for example a friends desktop.
<snip> I am WAY out of my depth here but that last paragraph is really interesting and I wonder if it provides an opportunity for X2Go to think outside the box. Why do we need NX? To forward X traffic in a WAN friendly way to the remote X Server. So, what if we bypass it completely - completely eliminate the need to transmit, cache, compress, optimize X traffic. Does the above mean we can just us our SSH forwarding to send the Wayland traffic to a compositor on the remote side and not worry about X over a network? - John
Nope. Wayland is not network transparent.
For network transparency you would still have to layer X on top of Wayland.
<snip> That part I get but what do they mean with they speak of communicating with a remote compositor and thus being able to forward native Wayland applications? - John
I saw that in Wayland discussions but I have yet to see any type of full-fledged demo.
Many of these discussions are pie-in-the-sky type wishful thinking by Wayland proponents.
And I think they will find this is somewhat more difficult than they have envisioned. It's one thing to implement the Wayland concept on the local machine and quite another to run it remotely.
Both the local and remote ends have to have the same idea of what is the display. Does that mean they both need the same GPU? Don't know.
We'll need to wait until someone has a true network-transparent demo of these new concepts before we can get excited about them. And since Wayland keeps stating to the "network-transparency" inquirers that it is not part of their requirement I don't think we'll see anything anytime soon.
