Sorry i missed it, it is rather mechanical approach to QG, which
has some appeal to me, but i guess it will stay on the book shelf,
shame really i like furry little quib its.
May I invite you to also take a look at the article I flagged right after that one (25 January) here

Reconstructing Quantum Geometry from Quantum Information: Spin Networks as Harmonic Oscillators
Florian Girelli, Etera R. Livine
16 pages, revtex, 3 figures
"Loop Quantum Gravity defines the quantum states of space geometry as spin networks and describes their evolution in time. We reformulate spin networks in terms of harmonic oscillators and show how the holographic degrees of freedom of the theory are described as matrix models. This allow us to make a link with non-commutative geometry and to look at the issue of the semi-classical limit of LQG from a new perspective. This work is thought as part of a bigger project of describing quantum geometry in quantum information terms."
Instead of being put off by not understanding it, try to get the drift. Here is a quote:
----quote from Livine Girelli---
A possibly relevant point of view is provided by quantum information. It appears that
many mathematical tools and physical questions are actually shared by loop quantum gravity and the quantum information field, and it could be helpful to develop an explicit bridge between these two research areas. This defines a project to reformulate quantum geometry in terms of entropy, entanglement and quantum reference frames. The present work is thought as part of this bigger project. We seek to understand the geometry of spin networks at the kinematical level. We reformulate spin networks in terms of harmonic oscillators and we show how the boundary degrees of freedom in LQG are described as matrix models...
... In a last section, we explain how quantum reference frames should allow us to localize systems on a spin network background and end with the idea that a notion of distance could be constructed on a spin network can be constructed in terms of entanglement between parts of that spin network.

I think Livine Girelli hit a rich vein here.
