We describe an implementation of a deconstructed gauge theory with charged fermions
defined on an interval in five dimensional AdS space. The four
dimensional slices are Minkowski, and the end slices support four
dimensional chiral zero modes. In such a theory, the energy scales
warp down as we move along the fifth dimension. If we augment this
theory with localized neutral 4-dimensional Majorana fermions on the
low energy end, and implement a Higgs mechanism there, we can
arrange the theory such that the lightest gauge boson mode and the
chiral mode on the wall at the high energy end are parametrically
lighter than all the other states in the theory. If this
semiclassical construction does not run into problems at the quantum
level, this may provide an explicit construction of a chiral gauge
theory. Instanton effects are expected to make the gauge boson heavy
only if the resulting effective theory is anomalous.
