--- Comment #2 from Peter Hutterer <peter.hutterer at who-t.net> ---
There is an experimental plugin for handwrite in ibus here:
https://github.com/epico/ibus-handwrite
and a Fedora COPR
http://copr.fedoraproject.org/coprs/pwu/handwrite/

fwiw, I had to yum reinstall "ibus-*" after installing from source, that
triggers something to get the engine listed. Then you can add it to the IME in
GNOME and trigger the binary in src.

Long story short: this displays a touchpad-shaped surface that reflects the
touches and translates it to characters. So once the touchpad is in that mode,
the input would be fixed-focus but can be surface-relative. Of course, ideally
the surface displayed should mirror the actual shape of the touchpad which
isn't possible through the wayland protocol yet.

So I think wl_touch as a protocol may just be fine, but whether we make it a
side-channel or how to transmit the size of the touchpad is an open question.
Plus the bit to ask the compositor to switch the touchpad into that mode, and
which device to switch to that mode.
