We argue that the physics of these moduli cannot be separated from the issues of dynamical and gauge mediated supersymmetry breaking. To illustrate this point we present a modified version of the type IIB KKLT model where the criteria for gauge mediated SUSY breaking may be realized.References added, 18 pagesHigh Energy Physics - Theorytext
