Introduction {#sec:intro}
============

The large hierarchy between the Planck scale where quantum gravity effects are important, and the scale where the electroweak symmetry is broken, drives the wealth of models at the electroweak scale, and motivates the Large Hadron Collider (LHC) experiments. While weakly coupled supersymmetry remains a leading candidate to stabilize the hierarchy, the Randall-Sundrum (RS) models of a warped extra dimension [@Randall:1999vf] have recently emerged as a fascinating alternative, which may be connected to string landscape solutions of the cosmological constant problem [@jmr], and possess an interesting four dimensional dual interpretation in terms of the composite states of a strongly coupled nearly conformal field theory (CFT) [@Arkani-Hamed:2000ds].

The original RS model had all of the Standard Model confined to the IR brane (appearing as composites in the dual description). However, the RS solution to the hierarchy problem requires only the Higgs to be localized at the IR boundary, and there are compelling reasons to consider most of the SM might actually lie near the UV brane (and thus mostly fundamental with respect to
