Do you have a radio?
But such a requirement is a niche and not the use case of 95% of users and as the other poster adds is easily accomodated by running a specialed X server on top of wayland.
is to provide display management for linux devices that generally do not require network transparancy such as phones and tablets and which are resource constrained so the bloat of a full xorg stack is unacceptible. Clearly Ubuntu which has designs on becoming the tablet king is embracing this - Fedora also has an interest because it is the basis of the olpc, raspberry pi and other lightweight device spins. The obvious simple way to support network transparency is to run an X server as a Wayland app and this works fine so backward compatibility is easy to provide in fact Gnome is adding westin support into mutter so apps will use wayland if available and X if not. Going forward adding network transparency nativly to wayland is a fairly trivial and can be implemented more efficiently than X - according to the developers.
Plusses: smaller leaner and simpler code base, backward compatibility for legacy X apps, possibilty of network transparency not based on what was state of the art 30 years ago. Tight integration into linux.
Minuses: linux only (possibly), some pain in the transition possible while support is added to distros. Developers currently focussed on solving specific problems for Tizen.
All the simple programs have been written.
