We show how, by breaking the SO(4,1) Lorentz symmetry in the bulk and introducing a Z_2 ``mirror'' symmetry, a potentially realistic model arises, in which all these problems are solved.4 pages, 1 figure, to appear in Proceedings of SUSY06, the 14th International Conference on Supersymmetry and the Unification of Fundamental Interactions, UC Irvine, California, 12-17 June 2006High Energy Physics - Phenomenologytext
