We investigate a new way of realizing a period of cosmological inflation in the context of brane gas cosmology. It is argued that a gas of codimension one branes, out of thermal equilibrium with the rest of the matter, has an equation of state which can---after stabilization of the dilaton---lead to power-law inflation of the bulk. The most promising implementation of this mechanism might be in type IIB superstring theory, with inflation of the three large spatial dimensions triggered by ``stabilized embedded 2-branes.'' Possible applications and problems with this proposal are discussed.
