Cosmological models with variable EoS

    An interesting and well presented new paper by Kumar and Xu:
    "Observational constraints on a cosmological model with variable equation of state parameters for matter and dark energy" http://arxiv.org/abs/1207.5582
    The idea of a variable equation of state for matter and dark energy is not revolutionary - e.g, "Cosmological model with variable equations of state for matter and dark energy" http://arxiv.org/abs/1204.0589 by Ponce de Leon. I find the continuity and consistency with observational evidence in modeling effects from high z to the modern era appealing.
