Thanks Tom.
I would characterise my strategy as extending and complimenting Bell's hidden variable theory approach because his indirect assumptions preclude certain physical possibilities. His main target seemed to be the EPR desire to banish probabilities from physics and restore determinism. My hidden propagator dynamics approach reaches exactly the same conclusion on this point - determinism in experimental predictions is gone forever. I don't have any problem with what Bell did; the issue is that his conclusion doesn't have the status of universal generality claimed for it - it is on this that we agree.
My HPD approach extends Bell's analysis in a new and interesting way that leads to inevitable conclusions when the logic is followed in physics. My intention was to reach for those conclusions, of which one is that a "unified theory" is inevitably extra-dimensional. The other big conclusion that I didn't have room to discuss in my essay is to do with the nature of locality in underlying reality and experimental reality.
All the best
