On the other hand, I think, even having detedted primordial non-gaussianity in CMBR mae not imply a must for nontrivial topology - since many more elaborated inflation models (trying to avoid the fine tuning problem) can introduce non-gaussian signal. In that cases the probability of some particular multiconnected topology detection falls.
i definitely agree that significant non-gaussianity in the CMB is not *sufficient* to show that there is observable nontrivial topology. It's also not a very good test for topology.
But there are many people claiming the observation of non-gaussianity is there in WMAP, independently of what the physical explanation is.
