We construct explicitly time-dependent exact solutions to the field equationsof 6D gauged chiral supergravity, compactified to 4D in the presence of up totwo 3-branes situated within the extra dimensions. The solutions we find arescaling solutions, and are plausibly attractors which represent the late-timeevolution of a broad class of initial conditions. By matching their near-braneboundary conditions to physical brane properties we argue that these solutions(together with the known maximally-symmetric solutions and a new class ofnon-Lorentz-invariant static solutions, which we also present here) describethe bulk geometry between a pair of 3-branes with non-trivial on-braneequations of state.Comment: Contribution to the New Journal of Physics focus issue on Dark  Energy; 28 page
