[SERVICE] Payment processor which allows selling of ebooks from the cloud

Paspagon is a payment processor which allows anyone to sell any file from the Amazon S3 cloud. No additional servers are needed, so after configuring a bucket it is possible to upload an AZW3/EPUB/MOBI/PDF/HTML file (using either the Amazon Web Services Management Console or an external tool like Cyberduck) and then point potential readers to the payment generation page (using either own website, a blog, Facebook, Reddit or by any other means). The payment process itself is also smooth, as a reader needs only to scan a QR code with his mobile cryptocurrency wallet and confirm payment. Having that done, file download is started automatically. A few examples are available.

Questions, suggestions and other comments are appreciated.
