Charm dynamics is moving back into focus with the established discovery of oscillations in the neutral D meson system and the sign of direct CP asymmetry in D0 to pi+ pi- / K+ K-. It opens the possibilities of finding CP violation beyond the reach of the Standard Model. In the recent past we have extensively studied charm dynamics within non-ad-hoc models with interesting flavour structures. We have shown that rare decays and CP violations are the best places to probe for New Dynamics in charm. We continue to study a different class of models, i.e., the Randall Sundrum model with a warped extras dimension to check for unusual effects in charm dynamics: namely in decays of final states with leptons and neutrinos and some asymmetries. These states should typically be accessible to experimental probes in the near future and, for certain, to any super flavour factory.
