  We examine the cosmological consequences of an alternative to the standard
expression for bulk viscosity, one which was proposed to avoid the propagation
of superluminal signals without the necessity of extending the space of
variables of the theory. The Friedmann equation is derived for this case, along
with an expression for the effective pressure. We find solutions for the
evolution of the density of a viscous component, which differs markedly from
the case of conventional Eckart theory; our model evolves toward late-time
phantom-like behavior with a future singularity. Entropy production is
addressed, and some similarities and differences to approaches based on the
Mueller-Israel-Stewart theory are discussed.
