The key is "more than one user".  As I mentioned below, assuming that
the only user is the networking bits (we can continue to discuss the
tty caller in the tty patch), this should live with the networking
bits; it makes no sense to keep it separate in that case.  Of course,
if there is more than one user, then keeping this change separate is
reasonable.
