Aside from all of the business and legal sticking points that others have
mentioned, there are also the technical aspects of capturing, storing,
transporting, analyzing, and managing those packets, and the appliances
that do the heavy lifting. As your traffic grows, that problem scales
1:1 linearly, at best, and more likely n:1 linearly, or worse. The added
overhead of the infrastructure needed to support this will also make it
more difficult to be price-competitive with your peers.
Your sales/marketing/executive staff would have their work cut out for
them in trying to explain to existing and prospective customers not only
where the value-add is for them, but why that would be worth the
significant recurring costs you'd have to charge to cover your overhead
and/or maintain your profit margin.
