Dan: I'm not sure what exactly is being proposed. Actually I think that there is some confusion in the fundamental physics here, as well as in the positivistic assumptions being invoked by Caledonian. If physics is reversible I don't think that something can ever go from being part of my light cone to not being part of it. The photons future doesn't impact me past some point, but the past of the future of that photon does. I suspect that when you use causality diagrams, or just do the math, any confusion here goes away.
