I will stress accent on point John made. My prev. comments do not impact ARS value. Even if customer wants to have metadirectory solution/umbrella over multiple platforms, the ARS lives on one floor below at AD/Windows room, and customer will have a strong case to have ARS in parallel to IDM. ARS is not IDM metadirectory solution, but operational AD management tool, which cannot be replaced by big guy IDM and coexists in parallel with IDM.
