Just want to stress this point, if you have a LJ cut-off of around 1 nm, 
density will increase by roughly 2% if you turn on dispcorr. You could 
probably define an inhomogeneous dispcorr for membranes, as a matter of 
fact we have done something like that in the past for liquid on a quartz 
surface.
