I have a combined fe/be HTPC which also does torrents, xbmc and the
occasional bit of web browsing

When I want to force a shutdown I do it via irexec and a button on my
remote. The rest of the time I use a cron job, since mythbackend
doesn't go idle with a frontend connected. The scripts have become so
thorough that I usually let the machine turn itself off :-)

I'm using irexec and some scripts. During shutdown the machine gets
set to wake up before the next recording. My combined fe/be machine
won't shut down unless:
- the remote/mouse/keyboard are idle for 15 mins
- either mythfrontend or xbmc are running
- neither mythfrontend nor xbmc are playing a recording
- firefox is not running
- the backend isn't locked
- the backend isn't recording/transcoding/commflagging/fetching EPG data/etc.
- it's more than 5 minutes until the next recording
- there are no ssh logins
- there are no screen sessions
- no torrents are downloading in transmission (I don't worry about seeding)
The idle and not-currently-playing-a-recording checks are skipped when
forcing shutdown via remote, but otherwise it refuses to shutdown and
pops up a box telling the user what's happening.

I've been meaning to put it all up somewhere but the code needs a fair
bit of cleanup.

Want me to send it to you?
