Any way for a company to 'legally' make money for its shareholders.
If they are at a profit cap on their current product, start extorting money. What good would a 6000/608 product be, if a filter the size of a T1 was put on a main portal. I'm sure that it Bell South had its VoIP product out, there wouldn't b e a traffic issue, and they would be the first to cry foul if someone filtered their traffic.
