Hello. I have a few questions regarding your excellent product. I want to create a site where I can charge per music/video file (a bit like iTunes). Visitor's would come to the site and see a selection of media files, which they can buy individually for $0.99 each, which when purchased allows them to either watch/listen the stream in a player (such as JW Player), or download it. They could also subscribe to all media files on the site for a larger sum of money. Would aMember be a suitable backend for such a website? it seems so, but I wanted to double check.
