  We consider the action of the $q$-deformed Poincar\'e superalgebra on the
massless non-relativistic R-matrix in ordinary (undeformed) integrable $AdS_2
\times S^2 \times T^6$ type IIB superstring theory. The boost generator acts
non-trivially on the R-matrix, confirming the existence of a non-relativistic
rapidity $\gamma$ with respect to which the R-matrix must be of difference
form. We conjecture that from a massless AdS/CFT integrable relativistic
R-matrix one can obtain the parental massless non-relativistic R-matrix simply
by replacing the relativistic rapidity with $\gamma$. We check our conjecture
in ordinary (undeformed) $AdS_n \times S^n \times T^{10 - 2n}$, $n = 2, 3$. In
the case $n=3$, we check that the matrix part and the dressing factor - up to
numerical accuracy for real momenta - obey our prescription. In the $n=2$ case,
we check the matrix part and propose the non-relativistic dressing factor. We
then start a programme of classifying R-matrices in terms of connections on
fibre bundles. The conditions obtained for the connection are tested on a set
of known integrable R-matrices.
