DAMA/LIBRA has an on-going 8.9a annual modulation signal of their single hit rate
[1-3]. If this signal is caused by dark matter scattering off their NaI crystals, then
DAMA, when combined with other null direct detection searches, suggests that dark
matter is scattering inelastically to an excited state split in energy by 0(100 keV)
. Inelastic dark matter (iDM) is a testable scenario with XENON10 and ZEPLIN3
performing dedicated reanalyses of their data [4,5]. IDM will be decisively confirmed
or refuted in the XENON100, LUX, or CRESST science run this year [10,11].
