a switching regulator would generate less waste heat and present less
physical resistance in the dynamo. Maybe it's negligible, but it's not that
much expense to upgrade from a linear regulator.

I have one of these http://www.dimensionengineering.com/DE-SW050.htm
that I could try once I have a hub dynamo.
