Just read about a new application that can connect groups of friends in mini-p2p networks that are private and secure. This sounds a lot like WASTE or other applications. The difference between these applications is that Grouper can only stream the mp3s for you to listen to. It can however transfer other types of files.

There’s more news about this here. It should be noted that this is similar in concept to the ideas behind Mercora and Three Degrees, but something about this seems different. We’ll see if any of these can differentiate themselves in the marketplace.
