Communication Module

Axis 2 will be used as Web Services Engine
A monitoring system will be implemented to check net's status: which peer is on, which peer is off, stats, ...
Information will be pushed using a notification scheme: each time a peer shares a resource it is in charge to push this new shared resource's metadata to its "neighbours", then each "neighbour" push the information to other peers and so on. PHASE 2: implementation of a synchronization service to retrieve shared resource metadatas on demand. PHASE 3: synchronization service applied to a peer/group chosen by the user.
Security layer will provide only users authentication, all resources will be considered public, all user will have same privileges.
Cryptography will be applied only to resources transfer, not to stored metadata.
