I haven't because it violates my EULA, and probably just about every other residential EULA.

(I am assuming you are talking about a residential fiber Internet link, due to your description.)

Most probably. However, it's still an interesting concept.

If homes are resources (e.g., providing shelter, building wealth, etc.), then monetizing those resources makes sense. The utility of a home is packaged as a rental. The utility of the sun can be captured and sold with solar panels atop that house.

Fiber is also a resource. Symmetrical 1GBPS transfer speeds without a bandwidth cap is also unusual. There must be some arbitrage opportunity here.

If you can find someone, or some company, foolish enough to pay $12/min for a commodity they can buy for the same price you did, or less, hats off to you.

$12/minute isn't achievable. It's just the theoretical cap assuming maximum demand and $0.20/GB of transfer.
