Not sure. A node on the lan can't access shares on the user net guest, but
the guest may be able to access shares on the node ... this depends on the
protocol in question.

Windows shares have the additional complication that they have to be on the
same subnet, although I am not familar with Windows XP and above so they may
have removed this limitation (Samba removes this limitation if you set an option
in its config file).
