It shouldn't have much of an impact on the everyday consumer initially. If anything for the little guys like DCI, it ensures that their streams get just as much priority between the pipe leading into your house and to your ISP. IMO, this is an excellent thing.
For the providers like DCI, Netflix, Amazon, the key to getting quality content and priority content into the homes is going to be more related to how well their datacenter and servers peer with the internet backbone that routes traffic to the ISP. Watching a 1080p stream from a datacenter in the US that has one or two skips / hops to link up with backbone and Comcast uses is an entirely different (and better experiment) than trying to stream 1080p content from a datacenter in the EU that has a bunch of more nodes to pass through to get to Comcast.
Dependent on how those backbone providers peer with one another and the amount of bandwidth they have, it'll have an impact on the inhome quality. What I'd expect to see happen is they'll claim they need to purchase more bandwidth from their backbone providers and pass that buck along to us.
Working in the tech space, it's a good regulation to level set the playing field and make sure that every packet that makes it your ISP has an equal opportunity to get to your house.
