The original title, "State of multi-player Wayland" is a much better summary of the article. This ain't just about the pointers! In fact, the author is very explicit about that:

> I think there could be a term that’s describing this concept even better – in the title of this post, I picked “multi-player”, to make clear that it’s mostly about multiple people who are collaborating. I’ve also seen “multi-cursor” or “multi-pointer” (which are missing the keyboard component).

In fact, you can also have a different touch input devices per seat!

I'm not aware of actual hardware that would make this feasible, but if you invent a touchscreen which recognises between two people's different fingers, you could have a client which tracks who clicks where without any protocol changes.
