Much as you can run X within Wayland there's absolutely no reason why it's shouldn't be possible to build networking above Wayland. Even better, there's room for competing implementations - one could implement a framework which ships some sort of serialized OpenGL commands (client-side hardware rendering), fully rasterized windows (relying on the server's video hardware), or abstract primitives (like X). By providing a level of abstraction lower than that of X, Wayland provides a more flexible framework over which to implement whatever "long tail" of useful features the Linux community desires.
