We generalize the notion of almost disjoint family to the setting of arbitrary totally disconnected Hausdorff spaces. We present some results about the existence of such families on the Čech-Stone remainder of the integers. As an application, we present some modest progress concerning the open question of the injective dimension of the Banach space $c_0$. This is joint work with David Schrittesser.
