The main, or one of the main, arguments I hear about neutrinos flying faster than light is that it would violate casualty aka. time travel. The Light Cone is supposed to be broken, in that case, and impossible things happen. But, even if neutrinos do travel faster than c - all we need to do is to re name the "light cone" to "neutrino cone" or any other name, witch would be simply .. wider. or they dont travel at all faster. I dont know.
