Can my FreeRunner remind me to shut it down if it is still running at 22:00?

Well, there are ways around that, too.

As an example, your script could start by popping up an xmessage on the 
screen asking the user if he wants to shut down now, with a No button 
that stops the process, and a timeout in case the user isn't there. 
Then, it could call shutdown with a delay (e.g. shutting down in 5 
minutes instead of now), this will send a message to users logged in via 
other ways than X (e.g. via ssh), and can also be cancelled. The user 
would then have 5 minutes to cancel the shutdown (using shutdown -c), 
after that it would shut down on its own.

Of course, similar methods could be used to just give a reminder as 
well. E.g., use an audio player (aplay, ogg123, ...) to make a sound, 
and pop up a message similar to the one above (though perhaps without 
timeout, just the Yes/No buttons, or just OK if you want it manual).

I'll admit to not being very up on current events though, so there might 
be better ways of doing those things (playing sound, showing 
message/question, shutting down) in the framework, instead of the common 
*nix utilities I'm considering.
