I don't see anything revolutionary here. The main components are: - a discovery protocol, which is neither smart nor efficient. But people can provide their own if they want. Most deployed architecture are not pure P2P because they use some central servers keeping track of the various nodes. - a suite of services that can be used by the applications built on top of JXTA (e.g. persistent store, etc.) - a message-based mechanism (based on XML) to describe the wiring between nodes (pipes) - code on demand when they are using Java (but JXTA is not Java specific) I think that a good way to see how revolutionary JXTA is is to look at the applications built on top of it. For most (if not all) of them, it is reinventing the wheel. regards, Arnaud ----- Original Message ----- From: "Skip Tavakkolian" To: <9fans@cse.psu.edu> Sent: Wednesday, October 02, 2002 12:03 AM Subject: [9fans] Article in the Economist about Bill Joy > Sep 21st issue of The Economist has a technology article about Bill > Joy and the latest in the alphabet soup that starts with J, namely > JXTA.
