  An inclusive search for the non-Standard Model production of two isolated
leptons of the same electrical charge is presented. The search was performed
with 2010 collision data in the ATLAS detector at the Large Hadron Collider for
ee, e{\mu}, and {\mu}{\mu} channels. With 34 pb-1 of integrated luminosity, no
disagreement with the Standard Model prediction was found, and limits on the
fiducial cross section for generic same-sign production as well as four
model-dependent limits for models of new physics were set. An updated same sign
analysis with 1.6 fb-1 is underway and nearly complete for the {\mu}{\mu}
channel. With new event selection criteria, improved data-driven background
estimates, and significantly more collision data, the sensitivity is expected
to improve significantly beyond that of the analysis completed with data from
2010. Initial results from the updated analysis are presented.
