  We consider a Randall-Sundrum model in which the Standard Model fermions and
gauge bosons correspond to bulk fields. We show how the observed charged
fermion masses and CKM mixings can be explained, without introducing
hierarchical Yukawa couplings. We then study the impact on the mass scales
associated with non-renormalizable operators responsible for proton decay,
neutrino masses, and flavor changing neutral currents. Although mass scales as
high as 10^{11}- 10^{12} GeV are in principle possible, dimensionless couplings
of order 10^{-8} are still needed to adequately suppress proton decay. Large
neutrino mixings seem to require new physics beyond the Standard Model.
