The JXTA platform is an open network computing platform designed for peer-to-peer (P2P) computing. The JXTA platform standardizes the manner in which peers:

* Discover other peers
* Advertise Peer resources (Peer, PeerGroup, Service and Pipe Advertisements)
* Communicate with each other (Pipes)
* Cooperate with each other to form secure peer groups (group membership)

JXTAもはやいもので、2.3.1だそうです。P2Pのプラットフォームとして結構興味があるのですが、さわることもできていないという悲しい現実…
