Quantum mechanics permits nonlocality---both nonlocal correlations and nonlocal equations of motion---while respecting relativistic causality. Is quantum mechanics the unique theory that reconciles nonlocality and causality? We consider two models, going beyond quantum mechanics, of nonlocality: ``superquantum'' correlations, and nonlocal ``jamming'' of correlations. These models are consistent with some definitions of nonlocality and causality.
