I am a bit surprised to hear the view that NN would make it impossible for ISPs to differentiate. Many companies sell the same product and manage to differentiate themselves. If you took away the customer service aspect of Dell, what reason have they to exist?
Price and customer service is a good starting point for differentiate companies. Latency is an other point, since no ISP can have zero hops to every other ISP in the world, regardless of NN. The Internet is designed with routers in mind, and each router adds to the latency. Sadly there is currently little competition on latency, except of the world of stock trading.
For companies, there is the world of BGP. High reliability, anycast, and so on. Not something I see much competition on either. Providing network solutions for companies is something that ISP's don't tend to do (here in Sweden at least), yet much at the network edge could be provided by an ISP if they wanted to offer it.
