This sounds good, but often won't help since there is no guarantee that your
ISP will accept incorrect source addresses from you.  I think Wolfgang
mentioned anti-smurf filters.  If you start sending packets with a source
of 231.231.231.231 to your ISP at 123.123.123.1 they may just drop them on
the floor.  Or they might get dropped further upstream from them if they
are a small ISP.
