In this paper we study the impact of data that can be obtained from a charm factory on the determination of the Cabibbo-Kobayashi-Maskawa parameter \ensuremathγ from decays of the form \stackrel\ensuremath→BD0K where the D0 decays to specific inclusive and exclusive final states. In particular, for each exclusive final state f, the charm factory can determine the strong phase difference between D0\ensuremath→f and D0\ensuremath→f by exploiting correlations in \ensuremathψ(3770)\ensuremath→D0D0. This provides crucial input to the determination of \ensuremathγ via the interference of B^\ifmmode±\else\textpm\fi\ensuremath→K^\ifmmode±\else\textpm\fiD0\ensuremath→f with B^\ifmmode±\else\textpm\fi\ensuremath→K^\ifmmode±\else\textpm\fiD0\ensuremath→f. We discuss how the method may be generalized to inclusive final states and illustrate with a toy model how such methods may offer one of the best means to determine \ensuremathγ with O(108--109) B mesons.
