Kenyon Gyros were the first thing that came to mind but it's an old school solution and may be no better than VR or IS in a smaller format. Everyone else has chimed in with their experience so I will too. The VR (version) on my Nikon 200-400 has allowed me to get shots that were tack-sharp to as slow as 1/15s, from a crouch, bracing elbows on my knees. 1/60th becomes very routine, shooting with an F5 at 7 fps. Subject motion is then a real problem at these slower speeds, a slowly turned bobcat head that blurred comes to mind, in the middle of a sequence where the 1/15s shots were tack sharp.
Larger cameras don't have stabilized lenses outside of huge astronomy reflecting telescopes (with these they do something similar by moving sections of the mirror--called adaptive optics, IIRC from my years working at an observatory). Astronomically, another slick technology is to put the larger optic/camera in a gimbal, guiding it with a system of fast stepper motors, driven off a video camera and software that senses brightness changes as small as a 1/4 pixel of motion. Off the shelf commercial solutions are standard features of high end amateur telescopes today, works great for correcting drive errors and atmospheric perturbance on long exposures of stars, galaxies, nebulas. Works with film cameras, too, though few astronomers yet use analog capture.
