We study semi-classical communication in positivity-violating k-essencescalar field theories, with superluminal modes propagating on a rollingbackground. The self-interactions due to the non-linear nature of thesetheories pose a constraint on the rate of superluminal information transfer. Wederive a novel bit rate bound on superluminal communication within a conceptualmodel, to which a general class of k-essence theories naturally reduces. Ourresult implies the possibility that, even if these positivity-violatingk-essence theories may not possess a maximal information propagation speed,there is nevertheless an upper bound on the rate of information transfer.
