using KWin's wayland compositor under an X11 session?

[René J.V. Bertin]

Hi,

Is it possible somehow to use KWin's wayland compositor when it's acting as the window server of an X11 session? I understand that the opposite is possible. I have little idea about the technical feasibility of what I'm asking but that aside it for anyone like me who feels wayland isn't yet ripe to replace X11 completely (but who'd still like to start playing with it).

Thanks,
R.
