Offer Free Bootplate CDN?

We’re working on adding a Bootplate Content Delivery Network (CDN) option which would load all sorts of common or heavy-weight resources from a public CDN hosted with MaxCDN.  We’re a little unsure on the costs associated, but the idea and the technology seem sound.

Basically, we’d default all resources to load from their local versions.  If the site admin checks the “Use Bootplate CDN” setting box in the Theme Customizer, it’ll load all Bootplate resources (JS, CSS, placeholder images, etc.) from the public CDN–which we’d probably have to pay for.

What are the possible costs associate with offering this CDN up publicly?

Could we find a sponsor? What would they be sponsoring, exactly?  SHOULD we allow this to be sponsored?
