pitching an idea

I have written before about the need to stabilize the Monero price to promote wider usage. My idea is to create a service like i mentioned in that post where a product would be listed with a stable price for a week at a time and reserves would be kept to keep the price stable while the spot price is below the stable price. I will not hide that you may pay more for the product if spot price is higher, but you would also pay less if the spot price was lower (to a minimum reserve anyway).

Would you be interested in such a service?

As an example, at the time of writing a 12oz bag of gratuitas coffee is 147.54mXMR where this service would have it at 154.23mXMR (+4.51%) until Monday when the price would update again.

Edit: an extremely crude example can be found at feder8.me. It is not an SSL site but it has nothing private anyway.
