las2peer is a Java-based Open Source framework for distributing community services in a peer-to-peer infrastructure. It is being developed by the ACIS Group which is part of the Chair of Computer Science 5 at RTWH Aachen University. Main goals are easy development and deployment of services.
las2peer is a peer-to-peer network with no central instance that controls the network.
The network hosts multiple services that communicate with each other. It's easy to develop a new service that integrates with other services decreasing development time.
