The consequence of the FTL neutrinos CERN thinks they found at six sigma significance is not the breakdown of causality. You can have faster than light neutrinos without backwards propagation of information. This is not the end of normality, but a new normality, one where Lorentz invariance is broken. This would mean that there is a universal reference class that trumps but doesn't destroy relativity. If anything, a universal reference class seems like a stronger causal structure than relativity.

This whole thing would be so normal, that there's a pre-existing effective field theory called the Standard Model Extension. http://en.wikipedia.org/wiki/Standard-Model_Extension

is suggested WIkipedia skimming, http://blogs.discovermagazine.com/cosmicvariance/2005/10/25/lorentz-invariance-and-you/ is what gave me the intuition of the universal inertial frame.

I'm at around 10% odds on this whole thing seeming like weak consensus in 3 years and something like >80% odds (on a very very long bet) that locally possible FTL information travel is possible outside of the local structure of causality.
