  We consider the possibility of getting accelerated expansion and w=-1
crossing in the context of a braneworld cosmological setup, endowed with a bulk
energy-momentum tensor. For a given ansatz of the bulk content, we demonstrate
that the bulk pressures dominate the dynamics at late times and can lead to
accelerated expansion. We also analyze the constraints under which we can get a
realistic profile for the effective equation of state and conclude that matter
in the bulk has the effect of dark energy on the brane. Furthermore, we show
that it is possible to simulate the behavior of a Chaplygin gas using
non-exotic bulk matter.
