No it doens't exist yet, because acpi_hotkey is an X CLIENT that
simulates key press events using the XTest extension (or does it by the
XSendEvent function). So this solution will only work when the X server
and the machine running the X clients, run on the same machine.
Acpi_fakekey will neither work when more than two persons are running an
X session, because 1 ACPI event will cause 2 simulated key event (1 for
So my solution would be that an event device will be created
in /dev/input/ and for each acpi hotkey event, a key press event will be
written to that device. In other words: the X server will be able to use
an InputDevice for the ACPI hotkeys.
