shutdown -h now from a cron job on the server that's run on each client. The
server should have ssh keys installed for root onto the clients so it's
pretty easy to script up a shutdown process.

Alternatively, add a cronjob in the /etc/crontab for the clients that shuts
down daily at say, 8 pm. But then you must have time synched properly.

As long as the general population is passive, apathetic, diverted to
consumerism or hatred of the vulnerable, then the powerful can do as they
please, and those who survive will be left to contemplate the outcome.
