Is there a way to publish web content and simply make a profit?

I envision something like S3 (Amazon Simple Storage Solution), but where the content creator gets to set a price per download, and assign which Amazon accounts receive which percentage of the revenue.

It'd be great if the content creator could set their cut at zero, and then whoever is downloading the asset is paying exactly and only for the S3 download bandwidth.

Or if the content creator could estimate how many downloads they would get in a month, schedule cost amortization for the S3 storage cost as well, and build that right in to the download cost. If the actual download rate is much different, perhaps the amortized cost could be configured to adjust itself rapidly, slowly, etc.

Or if the content creator could set up an asset to pay for its own storage and bandwidth, with some initial allowance. As soon as the asset has a negative balance, the asset could be immediately deleted, so as not to incur any more costs to the creator. Or the creator could pre-empt this death, and withdraw revenue at any time.

And if you put that all together, the content creator could say, "Amortize the storage cost (1k downloads per month expected, but adjust at a medium pace), die when it runs out of money, but I want to make $0.10 off every download, $0.01 of that to stay with the asset to pay for its own storage during lean months, $0.01 of that should go to my editor's account, and the other $0.08 go to me."

And yes, Amazon might demand their cut for doing all of this processing.

If I'm playing a video game, and click to download a new map, some Amazon API could be used to ask me to confirm my purchase, and then download the asset. All completely transparently to the person who created the map.

If I'm browsing the web, an "are you sure, this costs $0.30" interstitial page could open, before allowing me to download. All hidden behind a simple URL.

My point being that if this were built right in to S3, rather than requiring an entire storefront and Credit Card processing, etc, this would make it trivially easy for content creators to share and profit from their work.

Does such a thing already exist?
