This could go into the same API. As you mentioned before, it must be
garantied that only the screen lock/saver app recieves key and mouse
events. Furthermore, the window should be always in front. No other app
should be able to place a panel or something in front of it. Maybe by
setting a window hint like WINDOW_ALWAYS_ON_TOP ...
I see it this way:
the two APIs ( for keyboard app and screen locker/saver) are compiled in
if wanted ...
the screen locker API allows ONE client to connect. This client gets
notified when it should take action( after no user action for x mins or on
command, for screen locker). It opens the locker window and waits either
for events or for a password. Then it deletes that window.
-- this thing could be also made linked in, if there is ne client/server
thing... --
