Some of the abstract entities in the theory can "propagate" faster than light but that is not the same thing as practical signaling. Also note that classical quantum theory is non-relativistic and a more careful theory must be used when investigating such matters. My understanding of the Bell inequalities is that they demonstrate the incompatibility of simplistic superposition (linear) quantum theory and relativity. In the above I have not bothered to take into account the demonstrable isomorphism between subluminal and superluminal speeds explained some time back in this mailing list.
