I have just been forwarded this paper by a friend of mine http://www.nature.com/nphys/journal/vaop/ncurrent/full/nphys3343.html. As I am not currently affiliated with an institution and I won't pay for the right to read research that should be public. In the meantime, I wanted to ask if anyone has read it and generally what's peoples thoughts on the experiment?

To me, I think this is likely to be a CERN type situation where "Neutrinos breaking the speed of light" experimental timekeeping error or something involving entanglement that they have not considered [I don't know the details yet]. Any thoughts?

Here is an on ArXiv freely available overview of the history of the delayed-choice gedanken-experiments, which contains also a description of different experimental setups.
