        Every ISP I have ever worked for and every ISP I have ever used has
eventually been convinced by me to come around to this policy. Do whatever
you want by default, but let trusted/clueful people opt out of it and just
get their IP datagrams from point A to point B.

        I personally wouldn't sign an agreement with an ISP that allowed them to
molest my traffic in this manner unless it allowed me to opt out of it. I've
seen the headaches such assumptions about what everybody else needs/wants to
do can cause.
