We assumes that the cold dark matter energy density on the brane is conserved, but the holographic dark energy density on the brane is not conserved due to brane-bulk energy exchange. Our calculation show, taking $Ω_Λ=0.73$ for the present time, the lower bound of $w_{\rm Λ}^{eff}$ is -0.9. This implies that one can not generate phantom-like equation of state from an interacting holographic dark energy model in non-flat universe.10 pages, no figure, some references addedHigh Energy Physics - Theorytext
