Interoperable P2P: Jxta
Troy writes: "This article went up today (on developerWorks) about the Open Source project called Jxta, which is a community-run attempt to build a utility application substrate for peer-to-peer applications. Anything with an electronic heartbeat can become a Jxta peer." A nice high-level overview of how Jxta is supposed to work.

For those who don't get what Jxta is good for, don't worry, it took me a while too, but I think I have it.
Jxta is an attempt to combine XML, Java, and Gnutella. Obviously, this unholy hybrid can have only one purpose - to make a computer program so slow time runs backwards!
