I am no physicist, but it is my understanding that quantum entanglement had already opened the door for FTL communications, it is only a matter of finding a working protocol since entangled is dependent of correlations (source and destination talking).
Fresh results from the OPERA collaboration once more confirm its previous confirmation of the faster than light neutrinos indicated by MINOS. The new findings, available here, also further confirm a particular scenario: The neutrinos do not travel with superluminal velocity all the way. They only ‘jump’ a small initial distance shorter than 20 meters, after which they settle back and travel as usual with speeds below that of the speed of light. This initial jump would occur at speeds that are more than ten times the speed of light, perhaps even millions of times the speed of light.

Ya know, science is always changing, and I can't wait to see a final verdict on this one. Part of me wants to see neutrinos emerge victorious through the skepticism. I don't want Einstein to be made a fool of either, but exceptions to rules always gives that little extra hope to let your imagination ponder that which is regarded as "impossible"

If i am correct in assuming that this still doesnt violate special relativity in any way due to neutrino's being chargless. They may appear to transmit information faster than light. According to the no-communication theorem these phenomena do not allow true communication; They still do not convey energy or information faster than light.
Wavefunction collapse can be viewed as an epiphenomenon of quantum decoherence, which in turn is nothing more than an effect of the underlying local time evolution of the wavefunction of a system and all of its environment. Since the underlying behaviour doesn't violate local causality or allow FTL it follows that neither does the additional effect of wavefunction collapse, whether real or apparent.
for space comunications you need some thing fast.
this is it. I would bet aliens use this to talk to there home world.

Unfortunately - this phenomena is just -barely- over the speed of light (or appears to be so). Hence why it is causing such a stir. It is faster... but only just. Which is why there is much speculation on how it might represent an error of some kind (systemic or otherwise).
Although, as reported in this thread, current indications are that the neutrinos were subluminal, as per expectation, for much of the journey, and actually traveled for just a few meters at many times (perhaps millions of times) faster than light.

So say the neutrinos can go faster than light, what would that change in our lives? Is there any application to it or would it just be a cool, random "did you know..."?
Oh and btw:
