The closest thing I know of is cfs (in the ports). It encrypts some
of the directory structures as well, which is usually desirable
because they can contain secret information as well (think of a file
named "CompanyX_Merge_Plans.doc"). I don't know if it's capable of
handling passphrases centrally as opposed to on a user-session basis,
but if so, you would need someone with the password present every time
you booted the machine.
