Will Wayland have network transparency?
Solution 1:
My understanding is that X will be able to run on top of Wayland as a client. See the diagrams at the bottom of http://wayland.freedesktop.org/architecture.html for example.
They only mention this in terms of being able to share input devices with X for backwards compatibility, but I presume it means that it will be possible to communicate with the X server over a remote connection even though it is running on Wayland.
Solution 2:
I do not know of any graphical application that I cannot launch over an ssh session. I, and probably everyone I know professionally use this everyday. Not just at work, but at home too. Compiz and other cool effects are a luxury. Network transparency for every single graphical application I might install is a requirement. RDP or VNC are unacceptable substitutes.
All I can see on this topic is comments like "don't worry about it because...[insert words that make me worry here].
What I want is for someone developing Wayland to publicly say "don't worry about it because "network transparency is a top priority for us." They know we want to hear that but they won't come out and say it without hedging.
Solution 3:
According to http://mmol-6453.livejournal.com/253081.html network transparency is on the list of things to do, it's just on the bottom of that list. If what is said there is true, we will eventually be able to connect graphically to another machine and run applications, but not immediately, and probably BEFORE X is dropped. I hope this is true, because like others here, I consider this to be a prime advantage to an X based system than others, such as Windows.
