  Within the framework of the Minimal Supersymmetric Standard Model (MSSM), we
explore a decoupling of the parameters into separate sectors that determine
consistency with collider data, the abundance of dark matter, and potential
signatures at direct dark matter searches. We consider weak-scale bino-like
neutralino dark matter, and find that annihilations via light slepton exchange
present a viable mechanism for obtaining the appropriate dark matter abundance
assuming a thermal history. Constraints and prospects for discovery of these
models are discussed, including the possibility that direct dark matter
searches may be sensitive to these models if light squarks exhibit left-right
mixing. Differences between the scenarios presented here and the typical
expectations for the MSSM are discussed.
