  We consider a modified Randall-Sundrum (RS) framework between the Planck
scale and the GUT scale. In this scenario, RS works as a theory of flavour and
not as a solution to the hierarchy problem. The latter is resolved by
supersymmetrising the bulk, so that the minimal supersymmetric standard model
being the effective 4-dimensional theory. Matter fields are localised in the
bulk in order to fit fermion-mass and mixing-data. If $R$-parity violating
terms are allowed in the superpotential, their orders of magnitude throughout
flavour space are then predicted, resulting in rich flavour textures. If the
$R$-parity violating contributions to neutrino masses are somewhat suppressed,
then lepton-number violating models exist which explain the neutrino
oscillation data while not being in contradiction with current experimental
bounds. Another promising model is one where baryon number is violated and
Dirac neutrino masses result solely from fermion localisation. We sketch the
likely discovery signatures of the baryon-number and the lepton-number
violating cases.
