To nitpick, the wall itself is moving away at about one light-year per year. The photons that are not moving from our perspective because they are receding away from us at the speed of light will soon find themselves in a space where they are again moving towards us.

"we routinely observe galaxies that have, and always have had, superluminal recession velocities" -- Davis & Lineweaver.

Are you sure about that? While there may be a "neutral zone" where that's the case, it's only a small percent of the stuff that's beyond our senses.
