  Inelastic dark matter, in which WIMP-nucleus scatterings occur through a
transition to an excited WIMP state ~ 100 keV above the ground state, provides
a compelling explanation of the DAMA annual modulation signal. We demonstrate
that the relative sensitivities of various dark matter direct detection
experiments are modified such that the DAMA annual modulation signal can be
reconciled with the absence of a reported signal at CDMS-Soudan, XENON10,
ZEPLIN, CRESST, and KIMS for inelastic WIMPs with masses O(100 GeV). We review
the status of these experiments, and make predictions for upcoming ones. In
particular, we note that inelastic dark matter leads to highly suppressed
signals at low energy, with most events typically occurring between 20 to 45
keV (unquenched) at xenon and iodine experiments, and generally no events at
low (~ 10 keV) energies. Suppressing the background in this high energy region
is essential to testing this scenario. The recent CRESST data suggest seven
observed tungsten events, which is consistent with expectations from this
model. If the tungsten signal persists at future CRESST runs, it would provide
compelling evidence for inelastic dark matter, while its absence should exclude
it.
