If gauginos are discovered at the LHC, then it is highly likely that it will be only through indirect means that we can determine whether their masses are Majorana or Dirac. It is therefore important to understand what models can lead to this latter, relatively neglected, possibility; I shall describe work in this direction in the contexts of gauge mediation and "deconstructed gaugino mediation," where Dirac masses are particularly natural (since they allow the supersymmetry breaking sector to preserve R symmetry).
