That sounds like a good simplification. I like the idea of limiting the horizon to the stopping distance, though unfortunately it's not a straightforward calculation as of now. The big complication is that the blends are constant speed, so only a portion of each move can have acceleration / deceleration along the path. That makes it hard to know a priori how many segments we need to queue up, since some short segments may spend most of their distance in a blend. In principle, we could allow tangential acceleration during a blend, but it complicates the optimization. I'll look into it more and see if there's a good way to reliably do this.
For reversing a given motion, how far back would you need to go? A few segments or the whole path?
