Trasz, you are very good with uncomfortable question. Truth is, frevoke() syscalls is in the making for quite a long time, now. Behaviour shown in movie depends on cooperating services - xorg, audio server (pulseaudio) - for the time being.
+Tomasz Torcz But there must be a way to revoke a file descriptor? I believe it's neccessary even for standard ttys - to revoke the tty for background process when the user logs out.
Also - applications must be able to handle revocation and reopen the device when it's needed. Think about switching to another user (revoke) and then switching back.
