  We summarize some of the results we obtained in arXiv:1006.2126 (Physical
Review Letters 106, 071301), arXiv:1102.4637 (Physics Letters B 700, 150-156)
and in arXiv:1107.3334, giving complementary characterizations of the
relativity of spacetime locality that affects certain Planck-scale-deformed
phase-space descriptions of free particles.
