Harrison's chapter on the "cosmic box" in his COSMOLOGY textbook might 
be interesting in this context.

I've now finished reading the paper I mentioned a couple of posts back
in this thread, astro-ph/0310808.  The authors mention that the
cosmological time dilation---(1+z), independent of the cosmological
parameters---does not agree with the special-relativistic prediction
EVEN TO FIRST ORDER (Eqs. 3--5).  If so (and if not please point out
their error), then special-case cosmological models such as the Milne
model (i.e. lambda=0, Omega_matter=0; obviously a limiting case) cannot 
be expressed in the language of SR and agree with observations.
