  Recently, we introduced an ekpyrotic model based on a single, canonical
scalar field that generates nearly scale invariant curvature fluctuations
through a purely "adiabatic mechanism" in which the background evolution is a
dynamical attractor. Despite the starkly different physical mechanism for
generating fluctuations, the two-point function is identical to inflation. In
this paper, we further explore this concept, focusing in particular on issues
of non-gaussianity and quantum corrections. We find that the degeneracy with
inflation is broken at three-point level: for the simplest case of an
exponential potential, the three-point amplitude is strongly scale dependent,
resulting in a breakdown of perturbation theory on small scales. However, we
show that the perturbative breakdown can be circumvented -- and all issues
raised in Linde et al. (arXiv:0912.0944) can be addressed -- by altering the
potential such that power is suppressed on small scales. The resulting range of
nearly scale invariant, gaussian modes can be as much as twelve e-folds, enough
to span the scales probed by microwave background and large scale structure
observations. On smaller scales, the spectrum is not scale invariant but is
observationally acceptable.
