The answer was that they'd have an infinite wavelength (as if that makes sense) so they wouldn't literally be on a line in front of my face, but yet, they're there, alright, zero frequency photons flying at c in space expanding faster than they can travel, forever (according to the expanding theory).

Point is, the frequency redshifts. It will hit zero. That's consistent with what we observe out there. Known as Hubble's Limit.
