Mark,
Bladders and pistons have been done before in various applications.
Don't know of any main-stages that used bladders or pistons off the
top of my head. Though cryogenic bladders are a pain since there is
not a great many materials that remain very flexible at cryo. Pistons
also take up a considerable amount of mass and volume in your tank.
Others have also mentioned gas barriers, and stratifying the gasses to
act as a barrier. You need to have pretty specific requirements (like
the N2 sitting on the LOX for very long periods of time) for a
physical barrier to make sense.

Probably a dumb question...
..would it be possible to put some type of barrier between the LOX and N2 to
limit dissolving of Nitrogen?? The barrier wouldn't have to be perfect, just
good-enough.
