I was guessing about that. While reading about Wayland, I found this
extension:
https://github.com/01org/wayland-fits

And as you can read on the description:

"The first protocol is a interface for generating input events
on the server-side (e.g. mouse, keyboard, touch)."


What I was not sure if that would the one to go for accessibility needs,
and also if implemented as a private protocol, how at-spi2 could use it.
Or in other words, how declare at-spi2 as a trusted client.
