Partly supported by the Region PACA and INFN. To be published in Nucl. Phys. BWe show that the definition of a projective coordinate frame within a Laguerre-Forsyth scheme, leads to the extension of the factorized diffeomorphism algebra. The quantum improvement of this symmetry can be performed only if these coordinates switch, at the quantum level, into a non-commutative regime
