The two main complaints I see discussed here appear to derive from some fundamental misunderstandings about what Wayland is.
Wayland is a Protocol and an optional helper library to implementing that protocol. This protocol says nothing about net work transparency, in both the sense of enabling or prohibiting it. It also says nothing about client decorations. The key points here is not to make a decision for or against any particular technology or methodology and then be stuck with that decision for the next 20 years, like we are with X.
How or if, either of these work is all down to the compositor. The reference compositor 'Weston' does not do network transparency and leaves window decoration to the client or its toolkit. However none of the big desktops, i.e end users, will be using this compositor. For example KDE will continue to use Kwin as their wayland compositor, and KDE have already clearly said that Kwin will be decorating their windows and not the clients!
As to network transparency, all windows are drawn to their own back buffers, and where these buffers will be eventually displayed is also the choice of the compositor, and it might well just decided to send them over a network connection. e.g. like what VNC does.
I think if you base your opinion on what other people say, including me, then maybe you shouldn't comment? All of this is discussed first hand on the Wayland web site and/or mailing list.
Unfortunately since I've posted a bit late, I doubt many will read this...
