I am looking for the same thing. Even though I have the scene delay set to 0, SketchUp still pauses between the scenes. Kinda like a car coming to a stop sign - slow down, stop, speed up. Are there any plugins that will override this pausing?

As I said, not with skp files. There are a couple of 3rd party applications however that can do a walkthrough kind of presentation from SU - both free and commercial (and there are also 3D PDF solutions but they are best for product views - to rotate "from outside"). Would your boss be interested to spend a couple of hundred dollars for something like that?
