Yes. However, a method of reading pure IKBD scancodes for joystick, mouse
and keyboard (for all keys incl. Alt, Shift etc) from the system would
be helpful too. I of course mean a non-blocking call... Maybe AES could do
such a service installing an additional device in /dev or something...

I hope they will be kept.
