After installing libpam-ck-connector I can shutdown the
system via dbus-send.

I have a few problem with this:

- - it ignores process groups bound to a controlling terminal.

- - just because a user does not sit on the local screen his job is _not_
  less valuable than a local user. He shouldn't be ignored by default.

- - this is still Unix, so what about running
 'shutdown -h -t 60 "hey folks please terminate your jobs and log out"' ?

- - it ignores local services and virtual hosts (kvm, lxc, etc.)

- - What do you think will happen if a "local" user clicks on the shutdown
  icon (based on consolekit), but the system refuses to obey this command
  without any explanation? He will lean forward to press the power button.
  Of course he shouldn't and mustn't, but it shows that there is a big
  question mark behind the effort put into the shutdown procedure via
  consolekit.
