Downloader app for Amazon S3

Hi there,

I develop Kontakt libraries and I’m in the need of providing a better user experience for downloading / installing large files. I want an app for Windows and Mac where the user can log in, see the list of the products he/she has purchased and be able to download them. The app has to connect to the database in order to check all values (username, password, products and links), and has to download the files from Amazon S3 servers and extract them (zip or rar) in the location chosen by the user.

Please, contact me in order to discuss the details.
