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.
