There is an issue with the new paper by Bonzom and Smerlak on cellular quantization of geometry, which surfaces in an obscure footnote #5 on page 5 at the end. The paper http://arxiv.org/abs/1201.4996 appears to resolve most or all of the outstanding doubts concerning the Loop program. That would be too good to be true, so what's the catch? In what ways does their paper fall short of a full resolution? If you have some ideas about this, I hope you will share them. I'll start off by saying what I think is the main unresolved issue: concerning that footnote at the end.
