I sell a product to customers, and as part of this product I have a website where customers can upload data for processing. The data is of considerable size (gigabytes).
I am looking to buy extra bandwidth for my customers, and to make the arrangement with their ISPs myself so that the experience is seamless to the end users. Many of my customers are on university or corporate networks where they would be unable to make the arrangement themselves even if they wanted to. The extra bandwidth would apply only to connections to my website, not to the customer's other connections.
Basically I am looking for this sort of arrangement:
Is this sort of thing possible?
Edit: Now that the United States has ended net neutrality, is it possible?
