Telecom networks are opportunistic, without many orders of magnitude capacity upgrades, a paid prioritization scheme simply won't work, at all.
Since telecoms are looking to milk every last cent they can out of their current networks, I don't see that coming. The capex is way too large.
So this brings us back to what the whole Net Neutrality thing was about: access to peering instead of transit.
A properly effective Net Neutrality regulation would be one that requires ISPs to peer with anyone who otherwise meets their requirements, meaning that they don't get to pick winners and losers. This means Netflix or whatever else is next would be able to peer, if they covered the costs of facilitating it.
