DESCRIPTION:A recent study by Bojowald and Paily [1] provided a path towar
 d the identification of an effective quantum-spacetime picture of Loop Qua
 ntum Gravity\, applicable in the "Minkowski regime"\, the regime where the
  large-scale (coarse-grained) spacetime metric is flat. A pivotal role in 
 the analysis is played by Loop-Quantum-Gravity-based modifications to the 
 hypersurface deformation algebra\, which leave a trace in the Minkowski re
 gime. We here show that the symmetry-algebra results reported by Bojowald 
 and Paily are consistent with a description of spacetime in the Minkowski 
 regime given in terms of the kappa-Minkowski noncommutative spacetime\, wh
 ose relevance for the study of the quantum-gravity problem had already bee
 n proposed for independent reasons.\n[1] M. Bojowald\, G.M. Paily\, Phys.
