The abundant cold ice covering the Antarctic provides a tantalizing medium for Askaryan signatures of ultra high energy (UHE) neutrinos due to it's excellent rf transparency. RICE, a first generation radio array buried between 100 and 300 m near the geographic South Pole, took advantage of this natural resource and made great advances toward the realization of a GZK scale neutrino detector, establishing techniques for radio detection, and studying the properties of South Pole ice. However, an array large enough to be sensitive to the low flux of neutrinos at UHE would have to overcome the technical challenges associated with designing and operating a sparse array in a hostile environment, including power distribution, time calibration, triggering and readout over a scale of kilometers in temperatures of -50 C. Two other astrophysical neutrino experiments, ANITA and IceCube, have developed technologies and infrastructure that could be applied to making a large scale, englacial array a reality on a short time scale. In the coming austral summer, the AURA collaboration will begin deploying prototype antenna clusters parasitically on IceCube strings, using technologies adapted from ANITA and IceCube, as well as RICE, in order to establish the feasibility of a 100 square kilometer scale array.
