Yeah, I've seen that.
But an icon? I'm not sure where/how to do it...

Hm, but how to do that?
I've had a quick look at what the gnome tools do, but it really seems
overly complicated. Moreover, we want a simplified keyboard.
Maybe we could just have keycodes in the keyboard definition, and use
xlib to do the keycode to keysym lookup (that way, the layout of the
virtual keyboard is the one set in X), but AFAIK, keycodes are
vendor-dependant, and I can't find an xlib function to do KeyCode/KeySym
to utf8 lookup. Gtk has its own functions and tables to do that,
however, maybe we could use it, as it's already in d-i.
