  In a model-independent formalism of gauge mediation, Meade, Seiberg, and Shih
have shown that hidden sector effects are captured by two-point correlation
functions of the gauge current superfields and that, generically, many of the
characteristic features of gauge mediated SUSY breaking do not survive. We
review the general story, particularly the way that the correlators enter the
low-energy effective action and give rise to soft-breaking terms. We then
specialize to the case where there is a small parameter, F/m^2, where m is the
mass scale characterizing the hidden sector, and F is the strength of the SUSY
breaking. To leading nontrivial order in this small parameter, we show that
many of the classic predictions of gauge mediated SUSY breaking are recovered.
