Hi dehammer,
Probably not. The effect that these people are talking about depends on the radiation field that the photons are interacting with as they move along. The Hubble red shift is, I think, far too uniform for that.
By the wayHubble himself cautioned against too ready an acceptence of red shift as evidence of universal expansion. For other versions of cosmology have a look at
http://www.spaceandmotion.com/Cosmology-Big-Bang-Theory.htm There are some links on this page worth following.
My thinking on the subject is more along the lines of "how transparent is the vacuum of intergalactic space?" Everything from grains of dust, wisps of hydrogen, stray magnetic fields and on and on add a kind of turbidity to the otherwise pristine vacuum. On the one hand, this turbidity is a pain as it obscures the view. On the other side, it can tell us about the structure of space between here and there. Getting a "look" at the empty spots between the galaxies is quite a challange. What this paper suggest is that we might be able to distinguish optically the "quantum foam" that John Wheeler was talking about in in the 60s.
