Nice, I'll be looking forward to that. I always wanted to know more
about how Wayland is actually being used for IVI.

I thought that I'd just introduce the common/important compositors
(weston, mutter, KWin, sway maybe?) briefly. But I'll have to say a few
words about weston in particular anyway since it is the reference
compositor, so it could very well fit there.
