To me that seems a non-problem.  To itself, each molecule in an expanding 
gas appears to be at the center, and all other molecules are systematically
moving away from it with velocities that increase linearly with distance. 
Whether a "real" center exists or not is irrelevant, unless of course you
can actually see to the edge of the gas.  Our universe appears to be big
enough that the "edge", if any, is outside our light horizon.

Concerning the rest of this controversy, I think Ethan Vishniac settled all 
the dust in a later post.  Whether the galaxies are moving apart, or space 
is expanding, is just a question of how you choose to describe it.
