There has been a lot of flurry on retrocausality in the media that got me thinking about that issue once more. I suspended belief and for a few brief moments on champagne thought I really had it. But I was wrong ...

OK folks I woke up this morning realizing why my particular scheme without the coincidence circuit won't work. Very simple, same reason as usual. The noise from the receiver photons entangled with those sender photons that are absorbed by the stencil barriers will destroy the local signal. Of course, in the usual way of nonlocal interferometry the signal can be reconstructed after the fact with a proper design using data transmitted from the sender in the usual way. The only other loop hole would be if there were advanced EM signals, but if there were we would not have to go to all this trouble.

now online is a bigger file with references, illustrations and some more corrections and clarifications. This file will be continually updated expanded clarified and will be presented at Quantum Mind Conference in Salzburg and at the ISST Time Conference in Montery in summer 2007.
