Hi all, I just wanted to point out at the Hive2Hive library project over at GitHub. It is an open-source solution for distributed, P2P-based file synchronization and sharing, written in Java. In addition, it focuses on maximum security and privacy of both users and data. It supports the whole feature set known from similar centralized approaches, such as Dropbox or Google Drive, all packed in a clean, extendable API. I guess it is worth checking out...
