That brings us back to Stross' suggestion. The worst kind of Dawn Hunter scenario is probably that of a species that sends off a wave of self-replicating Nicoll-Dyson lasers to wipe out any competition. Worst because it doesn't require any exotic physics, so could be achieved by a species not much more advanced than our own.
