  We investigate the possibility that the entropy producing decay of a
right-handed sneutrino condensate can simultaneously be the source of the
baryon asymmetry, of gravitino dark matter, and of cosmological density
perturbations. For generic values of soft supersymmetry breaking terms in the
visible sector of 1-10 TeV, condensate decay can yield the dark matter
abundance for gravitinos in the mass range 1 MeV to 1 TeV, provided that the
resulting reheat temperature is below $10^6$ GeV. The abundance of thermally
produced gravitinos before and after sneutrino decay is then negligible. We
consider different leptogenesis mechanisms to generate a sufficient asymmetry,
and find that low-scale soft leptogenesis works most naturally at such
temperatures. The condensate can easily generate sufficient density
perturbations if its initial amplitude is $\sim {\cal O}(M_{\rm GUT})$, for a
Hubble expansion rate during inflation $> 10^9$ GeV. Right-handed sneutrinos
may therefore at the same time provide a source for baryogenesis, dark matter
and the seed of structure formation.
