I have now changed systemd git to consider key inhibitors taken by
processes which are not part of a session (i.e. taken by system
services) to be "global", i.e to be effective on all VTs the same way,
ignoring any active/inactive logic.

This should allow your tool to run as system service (which it does
anyway, right? after all it's doing system-global stuff). You'd still
have to fight out key handling between your code and GNOME/KDE, but at
least logind will stay out of your way then.
