Summary: 


At least two explanations have appeared for the slingshot effect that do NOT
involve a burn at the bottom of the planet's gravity well. It might at first
appear that this violates conservation of energy. In fact what happens is
that both energy and momentum are transferred from teh planet to the
spacecraft -- the planet *slows down* in response to the flyby.

I would be interested in seeing this worked out in some detail. Might even
do it myself if I have time.
