Bruno writes in the article Computation, Consciousness and the Quantum ( http://iridia.ulb.ac.be/~marchal/CC&Q.pdf )

``All sufficiently realist interpretations of quantum mechanics accept the existence of parallel situations.´´

I think that this is true for interpretations that assume that quantum mechanics is fundamental. However, 't Hooft has recently shown that it is possible to derive quantum mechanics from a certain class of deterministic models, avoiding the usual problems of hidden variables. In fact his theory doesn't treat particles as elements of physical reality at all. Particles only arise in the statistical treatment of the deterministic model. Therefore Bell's theorem doesn't apply. See:
