Sounds like the ways are access=private, and nodes where the gates
meet the roadways (I assume there are gates?) are barrier=gate,
oneway=yes.  I'm basing the oneway=yes from
http://wiki.openstreetmap.org/wiki/Barrier#Examples, though it's not
clear to me how the oneway part is supposed to be applied.  That
should be clarified.

The part about "once you're inside..." is, in my opinion, a red
herring.  Once you're inside, the assumption is that you must have had
permission to be there in order to have gotten there.  This is true of
any access=private road I can think of.
