Obviously we need to think about how we want this to work :) -- It is not clear to me that we want 3 of them. I imagine that we want an analysis that is precise for small problems and then degrades gracefully as the problems get larger (some some appropriate definitions of smaller and larger). On-demand updating is often preferable regardless (whenever doing so is cheaper than redoing everything).
