Exactly, and the reply is always from the point of view of the developer. They want to talk about what style of protocol or something that remote apps will use--I don't care. I want to know whether I can run programs the same way that I do now.
A subset of people like me use their desktop as primarily a terminal to connect to more powerful servers. I want to know if Wayland will let me "ssh me@oldserver-running-X xterm" and then use the remote xterm to start a bunch of programs that open their own windows. I don't want to know how it does it, only if it will work.
If the Wayland developers don't want to commit to making something like this work, that's fine. It just means Wayland isn't designed for me. If they *are* going to make it work, I would feel more comfortable is they would come and say for certain that they are committed to supplying this functionality.
This same point comes up again and again. I think that the developers at some level don't understand the question, because there never seems to be an answer that is straightforward and pitched at the level of the user. (Not that anyone *owes* me an answer. I am just making a request.)
