What would net neutrality enabling traffic prioritization look like?

A big thing at stake in the debate over a free, open internet like we've had on terrestrial internet service for a while and a closed, sectioned off internet like cellphone internet was back before iPhones and Androids has been prioritization of traffic and what it means for freedom. There are those who want the FCC or Congress to mandate that there's no prioritization so that a carrier like verizon can't make youtube artificially slow for their subscribers so you'd have to watch a pay on demand streaming thing instead. Or that an ISP with certain political leanings didn't favor their allies blogs over their rivals. There are carriers and ISP's who argue they need to be able to prioritize and throttle traffic to keep their networks operable and raise the cash to build out more infrastructure.

So there we have it. I by no means claim to know OSI or TCP/IP or how to craft policy at the level for whom it is their profession. But I do know how I would enable online democracy and create an information availability and integrity policy for a network I was administering. If there is to be compromise on internetworking policy issues I hope this is an informative and constructive document in the requisite debate. And be gentle. This is lower level networking than I deal with daily.
