run Terminal and type this to sleep after 30 minutes:

sleep 1800; killall -STOP iTunes

to resume itunes:

killall -CONT iTunes

Good for audiobooks at night I think. You could also do 'sleep $((30*60))'

Hey, in the iPhone Clock app, under timer, instead of playing a sound when the time is up, you can pick 'When Timer Ends... Sleep iPod'. That will pause an audiobook or podcast. Cool.
