Have you talked with cloudflare about this?

Lets say you become a huge hit and megaupload or vimeo or someone else with massive traffic (but not on the "we built our own datacenters and ISP CDN" level) start using your service. What then? Cloudflare will call you and demand you step up to an enterprise plan or pay for premium traffic.

Your pricing model assumes the pricing model of another pricing model that assumes pricing negotiation when usage increases. You will be the middle party in a discussion where you really don't control either party.

This is why I actually like AWS:es nickle-and-dime for every compute second and megabyte.
