  The fluctuation spectrum of membranes in nematic solvents is altered by the
boundary condition imposed on the bulk nematic director by the curved membrane.
We discuss some properties of single and multi-membrane systems in nematic
solvents, primarily based on the Berreman-de~Gennes model. We show that:
membranes in nematic solvents are more rigid and less rough than in their
isotropic counterparts; have a different Helfrich steric stabilization energy,
proportional to $d^{-3}$, and hence a different compression modulus in the
lamellar state; and can exhibit phase separation via unbinding during a quench
into the nematic state. We also discuss the preparation and possible
experimental effects of nematic-mediated surfactant membrane system.
