  DAMA observes an annual modulation in their event rate, as might be expected
from dark matter scatterings, while CoGeNT has reported evidence for a similar
modulation. The simplest interpretation of these findings in terms of dark
matter-nucleus scatterings is excluded by other direct detection experiments.
We consider the robustness of these exclusions with respect to assumptions
regarding the scattering and find that isospin-violating inelastic dark matter
helps alleviate this tension and allows marginal compatibility between
experiments. Isospin-violation can significantly weaken the XENON constraints,
while inelasticity enhances the annual modulation fraction of the signal,
bringing the CoGeNT and CDMS results into better agreement.
