Preferred Frame versus Multisimultaneity: meaning and relevance of a   forthcoming experiment
  It is argued that: 1) Quantum Mechanics implies the preferred frame also because of the collapse delayed at detection, 2) forthcoming experiments with moving beam-splitters will allow us to decide between Preferred Frame and Multisimultaneity, and 3) if the Preferred Frame prevails, superluminal communication is in principle possible.
