Neutrinos may be able to violate c according to some news out of CERN today. Now hypothetical particles that never drop below c wouldn't violate relativity. It's also possible that space-time is an emergent property of certain objects (Petr Horava). Neutrinos of this frequency might not emit space-time.
One thing is certain for the neck of the woods I'm in: now we seem to have one more entity in the universe that doesn't conform to what Martin Hagglund claims is the unbreakable law of succession given by Derrida.
There are of course many implications if this is verified. It looks already like it's more than likely.
