Finally I had time the read the
Cosmic Variance entry.
Evidently, I had read about the Supernova 1987A evidence, where neutrino's did not travel faster than
c, however they had something to add to that:

More relevant is the fact that we have completely independent indications that neutrinos do travel at the speed of light, from Supernova 1987A. If the OPERA results are naively taken at face value, the SN 87A should have arrived a couple of years before we saw the explosion using good old-fashioned photons. But perhaps we should resist being naive; the SN 87A events were electron neutrinos, not muon neutrinos, and they were at substantially lower energies. If neutrinos do violate the light barrier, it’s completely consistent to imagine that they do so in an energy-dependent way, so the comparison is subtle.

Which, I guess doesn't help settling the debate for now
