I'd like to confirm my understanding from one year ago, that the following is possible: 1) Using a combination of entanglement processes (entangling an already entangled particle with another already entangled particle, such that the outer particles, the other particles of each pair, will be entangled as well), one can effectively entangle two particles which have no common history. (Think of a "W" shape where the two sources of each of the two entangled pairs are at the bottom, and the four particles fly towards the top, with the two inner particles meeting in the middle.) 2) This is possible to do in a way that the correlation effect between indirectly entangled particles can be established before any signal can travel the whole distance (since the inner particles of each pair travel in opposite directions). And that it is therefore not possible that any "hidden variable" connects the outer particles within the speed of light before the measurement is taken, so that any local explanation for the correlation would have to explain this by what happens ("pairing-up") when the researchers meet afterwards to examine the results for correlations. In case I'm getting the question across, is my interpretation of the research done so far correct?
