Yep.  You can even connect two clients with different local keymaps and
it still works ;)

That is exactly the drawback ...

We can try that.  For the 102th/105th key on i18n keyboards we likely
have to create something.  For the extra keys the japanese keyboards
have we maybe can simply send the existing keysyms for these keys
(assuming the scancodes for these keys are unique, i.e. used on japanese
keyboards only).
