Yes. That's what I vaguely remembered. Another way of putting it is to think of it as not as a case of photons speeding up per se, but of the photons being displaced by the spatial inflation. They, along with the matter, are just going along for the ride. Measured in a local frame of reference, nothing was physically breaking the cosmic speed limit.
It's an almost lawyerly explanation to get out of a cosmic speeding ticket, doncha think?
Lawyers wouldn't do that well, trust me. But I see that there really is a difference with this space stretching business. Once the space has come into existence, photons would presumably be restricted to travel at c, within the existing space. But at the "frontier" it's different.
