This would be pretty fundamentally shocking to relativity, but I'm curious if the results of this experiment will prove reproducible.

I'm not an expert, but I'd guess it couldn't possibly mean what the articles make it sound like to people like us. I'd like to hear an actual physicist comment on whether a sub-c photon would necessarily have a rest mass. That, to me, would imply monster repercussions in energy transport.
