  A field theoretic understanding of how the radial direction in the AdS/CFT
Correspondence plays the role of a gauge invariant measure of energy scale has
long been missing. In SU(N) Yang-Mills, a realization of a gauge invariant
cutoff has been achieved by embedding the theory in spontaneously broken
SU(N|N) gauge theory. With the recent discovery of ghost D-branes an AdS/CFT
Correspondence version of this scheme is now possible. We show that a very
simple construction precisely ties the two pictures together providing a
concrete understanding of the radial RG flow on the field theory side.
