I've never ridden a dynamo hub, but I have a physics degree and know quite a bit about electrical engineering and resulting forces..

And no! Whether it's on all the time or not. It's the amount of charging done that results in a resistance in your dynamo. So when you plug it in occasionally, you get a higher resistance for a shorter time. Resulting in the same total resistance..

Plug it in at top of hill, unplug at bottom?

you'll have less speed at the bottom of the hill then when it's unplugged, leaving you to do more pedalling when you've reached the bottom ;)
