The implementation of various methods for the determination of gamma through direct CP violation arising in the interference of b->c and b->u processes in charged as well as neutral B meson decays are considered. We show that the inclusion of D0 resulting from D*0-->D0+pi0(gamma) say via B-->KD*0 makes a significant difference in the attainable accuracy for gamma. Both exclusive and inclusive decays of the B+- and B0 to states containing D0/D0-bar followed by both inclusive and exclusive decays of the D0 are discussed. It is shown that with statistics which might be obtained at B factories (5-10 X 10^8 B-pairs) a 1-sigma determination of gamma to about +-5 degrees may be possible depending on the efficiency of reconstruction, backgrounds and the details of the decay amplitudes involved. The role of data from a charm factory as well as effects of D0 mixing are discussed. Extraction of gamma with accuracy that is roughly commensurate with the intrinsic theory error of these methods (i.e. around 0.1%), which is an important goal, will require >10^{10} B-pairs, namely a Super-B Factory.
