 :Recently Austin showed that, for free probability-measure-preserving actions of countably infinite amenable groups, entropy is preserved under bounded and L^1 orbit equivalence, and more generally that an entropy scaling formula holds for stable versions of these equivalences. I will explain how Austin's geometric techniques can be applied to the realm of topological dynamics to show that,for topologically free actions of countably infinite amenable groups on compact metrizable spaces, topological entropy is an invariant of continuous orbit equivalence.
