I think the oil-cooled boxer (perhaps with some thermostatic control added) is an interesting compromise. Seems to comply OK with advantages of air cooling and liquid cooling. Perhaps the oil-cooled boxer twin (without doo-dads like counter-rotating shafts) is a design that deserves a future.

You don't need to be an enviro-nut to believe two-strokes are an abomination on the environment.
