I do not want to get into this terribly much, not because of lack of interest (this is connected to what I work on) but more because a sense of futility. There is one difficulty with all of this; inflation stretched space into a homogenous space that bears little data concerning what came before inflation. Any fluctuation associated with the state of the cosmos prior to inflation has been stretched to scales that may bear imprints on the CMB or they may even be larger. If this cosmos in the inflationary or pre-inflationary stage interacted with other vacuum bubbles or there were other quantum gravitational physics it might have an imprint on the CMB. The structure of anisotropies of the CMB temperature or amplitude does contain some statistical kurtoses that may indicate something beyond a white noise or Gaussian spectrum.
