Not a physicist, but my answer to you is that usually superliminal speeds is the price that physicists are willing to pay to explain what is observed in experiment. I get your objection to the rather convoluted argument that special relativity still applies to message transfer, but I accept it. John Preskill explains the information within entanglement with an analogy to a book. Normally with a book, you can read one page seperately from all the other pages. Further, if you unbound the book, and randomly distributed the pages to your friends, you could put your heads together and reconstruct the entire book. With a "quantum book", the information is encoded in the correlations between the observables, and you can only see the information when all the pages of the book are together and in the correct order. If you look at a single page of the quantum book, it's purely random gibberish, and you can't derive anything about the book by looking at a part of it.
