Nothing. Quality of service will remain, at worst, as it currently is, and no one will notice a difference. Netflix et al. will continue to host cache devices with ISPs, torrents will still work, video chat will still work, and chances are no startup will ever be forced to pay ISPs to deliver their packets. No one will ever be presented with the option to purchase a "Social Media/Streaming/whatever Internet Package," but maybe they'll be offered the option to upgrade to a more explicit SLA with bandwidth/latency guarantees. Maybe some kids will DDoS an ISP or two, but the effect will be nil. That's my prediction.
