I did see someone simulate a waterfall once with Poser 5 dynamic hair with a water material applied, of all things. I believe you can save dynamic hair just fine - just parent it to a prop, and save the prop. The "skull caps" are great for that. Yes, you can save a character and all its props together. Not sure about animating the camera. Maybe you can make it "point at" your figure, the way you can make props "point at" other props. Hope this helps, and have fun ignoring the trolls!
