  We consider the signals of positrons and electrons from "exciting" dark
matter (XDM) annihilation. Because of the light (m_phi ~< 1 GeV) force carrier
phi into which the dark matter states can annihilate, the electrons and
positrons are generally very boosted, yielding a hard spectrum, in addition to
the low energy positrons needed for INTEGRAL observations of the galactic
center. We consider the relevance of this scenario for HEAT, PAMELA and the
WMAP "haze," focusing on light (m_phi ~< 2 m_pi) phi bosons, and find that
significant signals can be found for all three, although significant signals
generally require high dark matter densities. We find that measurements of the
positron fraction are generally insensitive to the halo model, but do suffer
significant astrophysical uncertainties. We discuss the implications for
upcoming PAMELA results.
