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.9 pages, RevTeX; for the proceedings of the symposium on Causality and Locality in Modern Physics and Astronomy: Open Questions and Possible Solutions (York University, Toronto, August 25-29, 1997).
