  Recently, the DAMA/LIBRA experiment has convincingly confirmed the DAMA/NaI
annual modulation signal, experimentally demonstrating the existence of
non-baryonic dark matter in the halo of our galaxy. Meanwhile, in another part
of town, other experiments such as CDMS and XENON10 have not detected any
evidence for dark matter. One promising dark matter candidate which can
reconcile the positive DAMA annual modulation signal with the null results from
the other experiments, is mirror dark matter. We re-analyse the mirror matter
interpretation of the DAMA annual modulation signal utilizing a) the new data
from DAMA/LIBRA, including the measured energy dependence of the annual
modulation signal b) an updated quenching factor which takes into account the
channeling effect in $NaI$ crystals and c) the latest constraints from CDMS/Ge,
CDMS/Si and XENON10 experiments. We show that the simplest possibility of a
$He'$ (and/or $H'$) dominated halo with a small $O'$ component is sufficient to
fully explain all of the dark matter experiments. We also point out that a
certain class of hidden sector dark matter models, although theoretically less
appealing and less constrained, can mimic the success of the mirror dark matter
model and hence are also viable.
