Dave,
You might be thinking of a thread form me last December. You replied back then too, thanks. If you're thinking of a different thread, then maybe you can give me a unique key word to search for.
I got too busy last winter and am now finally implementing because the need is so acute. It could be that OIS won't handle the continual motion. New JVC Everio in addition to Panasonics have good stablization, but only for hard disk cameras I think. At first I won't have time (working 12-14 hour duty days, 10 on, 2 off) nor money for fancy stabliization, but I could at least attach the camcorder to the cushions of the seat for some dampening.
I'm not yet worried about the angle of view, but may maybe I should. Here is an example of a still shot today through a 35mm equivalent lens.
