We review results which explicitly depend on the entanglement of neutral meson pairs produced at the psi(3770) and Upsilon(4S). Time-dependent CP-violation analyses at the B-factories use the flavour-singlet final state at the Upsilon(4S), but by assuming its quantum-mechanical evolution; Belle on the other hand has tested the time-dependent flavour correlation of the B-mesons, comparing predictions of quantum mechanics, spontaneous disentanglement, and Pompili-Selleri models. At the psi(3770), decay rates are modulated by various combinations of the charm mixing parameters: this has been exploited by CLEO-c to provide the first effective constraint on the strong-phase difference delta. Finally, the goal of a "model-independent" phi3/Dalitz analysis is now within reach, using D-mesons from the psi(3770) to constrain the D0 -> KS pi+ pi- decay amplitude. Manifestly entangled events psi(3770) -> (KS pi+pi-)D (KS pi+ pi-)D, rather than just "CP-tagged" decays, turn out to be crucial.
