It is also likely to have some relationship to Maxwell's demon 
(daemon?), methinks.

This is the guy who monitors the shuttered hole between two gas 
vessels, opening it when a hot molecule approaches from the left
vessel and closing it when a hot molecule approaches from the
right (or vice versa).  Net is a temperature difference which
can be used to run a heat engine => perpetual motion.  (Don't
worry; Leo Szilard used information theory to prove that it 
takes more energy to run the demon than you get out.  Second 
law is safe.)

Some physicist will probably correct the errors I made in that
description ;-)
