That would not work. Most users don't care/don't know about about QoS, nor they want to learn. There was/is a ton of research on user-driven QoS, micro-payments, per-flow reservations, etc. etc. The result: there is no nice or simple scheme to a) expose QoS knobs to users b) align incentives of ISPS/ContentProviders/Users for micropayments, c) affordable equipment that can do per-user crediting across the Internet.

On which specific part?

E.g. networking research has ton of these kind of papers: http://conferences.sigcomm.org/hotnets/2006/estan06achieving...

They never go beyond modeling and simulation because, if you read such works, you can see that it is extremely hard to adopt such schemes.

Even between ISPs and content providers they endup with just 2-3 major pricing Tiers, because the added benefit if accounting more tiers is diminishing: http://conferences.sigcomm.org/sigcomm/2011/papers/sigcomm/p...
