That sounds pretty much like high application stuff. If I had that in my mind,
I would not have had asked in linux-KERNEL. For an application it's easy to
have some directory.

The solution you're proposing is good and elegant --- in it's domain. It
solves one narrow problem. I need a solution that is broader. Your solution
wouldn't work with Qt/Embedded apps AND X11 apps AND ncurses apps. Maybe
because your hardware is only used for playing mpegs. But what if the
computer is used for tn-5250 (ncurses), Konq/Embedded (Qt/Embedded) and Java
(X11), just as the user pleases? In this case you need something general,
and that usually means a kernel driver (because, in our case, there is no
kernel interface for a user-space program that can inject key codes back into
the kernel so that the keycodes would be subject of normal
controlling-tty-handling).
