Olympus Looking into Making Lens Shake a Useful Feature

Olympus recently filed a patent in Japan for a novel lens feature that shakes the front element in order to remove droplets of water.

Filters would obviously render the shaking feature useless on a DSLR system, but for a smaller compact camera designed to be waterproof and rugged, this feature would probably come in handy.

The patent also seems to indicate that the shaking would occur during autofocusing, so the lens would be cleared of water immediately before the camera exposes a shot.

What are your thoughts on this potential future feature?
