Currently the only way to get 2-way interactions with cloth and PhysX is to create your cloth but set the binding strengths to 0 (or even de-activate the particles), then apply PhysX shapes to the particles and re-bind them with PhysX binds. So the initial Cloth Bind sets up the cloth driver particles, but PhysX handles everything else. It's hacky but there's no reason why you couldn't get an acceptable result for simple setups. The biggest drawback is the speed of the solvers....the native bind solver can handle hundreds of thousands of particles pretty easily, however PhysX is going to run like molasses once you get above 10-20k particles on a beefy machine. So for cloth that has a large number of vertices it may become frustratingly slow.
