It seems that most people do not have problems with IS(v1) lenses mounted on a tripod. There might be several reasons for that: 1) The tripod is not very stable 2) Wind 3) Somebody walking close by (especially on hardwood floors) or heavy traffic passing by close (for example heavy trucks, trains, etc.). 4) Shutter is released directly on the camera and not with a cable release 5) Not using mirror lock up etc. If the IS works for relatively small amplitudes and/or higher frequencies (compared to handholding) then in the above cases no negative effect of IS would occure, as a matter of fact it would even be helpful. Only for long exposures without constant external disturbances (traffic, wind, etc) or if one is very careful (MLU, cable release, sturdy tripod, etc) IS can mess up the picture. Just some thoughts...
