This effect could allow existing and proposed supernova neutrino detectors to provide new insights into the problem of shock re-generation and propagation. Alternatively, such observations could allow unique insights into the neutrino mass and mixing matrix.4 pages, 3 figures, revtex4, submitted to PRLAstrophysicsHigh Energy Physics - Phenomenologytext
