I like the idea; I'd like more information on the implementation

Do you so this by adding an "interface list" field?

Do you run as other-than-root before you do this?  Root can escape
a chroot jail because of the way the chroot root vnode is (in my
opinion) incorrectly set to NULL instead of the real root for the
non-chroot case (fixing this would incidently simplify the namei code).

The "ftpd" case is especially vulnerable...
