We calculate the mean free path of neutrons and protons in symmetric and asymmetric nuclear matter, based on microscopic in-medium nucleon-nucleon cross sections. The latter are obtained from calculations of the G matrix including relativistic ``Dirac'' effects. The dependence of the mean free path on energy and isospin asymmetry is discussed. We conclude by suggesting possible ways our microscopic predictions might be helpful in conjunction with studies of rare isotopes.
