I suggest looking into lambda circuits/lambda switching. The path between the customer and the provider is not shared, and can be reconfigured to switch providers. What is shared between customers are the links from the provider's point of presence to the provider's backbone to the internet, and the quality of those links is one of the things that providers can use to differentiate their service. The scarce resource is space at the handover point between the utility and the provider, and that's something that would have to be regulated. But it's a fixed cost based on physical space, not on per-byte counts or somesuch.
