Thanks send me the code.

If you use '-S' ntop will resurrect the instances from disk as needed
(i.e. when there's traffic for such hosts).

My idea is to integrate -S with DB support (i.e. UPDATE). Anyway the DB
support will be moved out of the ntop core after ntop 2.0 will be
released as the ntopo core is too fat and this functionality can be very
well implemented externally (e.e. using Perl).
