Depending on your edit platform, there are some programs to smooth out camera motion, while maintaining in-scene movement or pans. Depending on the size of the "bump", you may have to sacrifice some image size.

In the end, it's a trade-off of how annoying the bump is, compared to the slight degradation of the image during motion stabilization editing.

I frequently find areas of vibration in factories/boats where you just can't use the tripod...and it's back to the organic stabilizer located on top of your shoulder...

Like it has been mentioned, optimal vibration damping (suspension/friction) is tricky, and depends on the the vibration spectrum/amplitude and the mass to be stabilized. New cams like the Sony NXcam, Sony XR500/520, Panasonic TM350 have "active mode OIS". This new approach is up to 10 times as effective as the standard OIS and should solve most of the vibration problems mentioned in this thread. I own XR500 and the difference is indeed impressive.
