Napigator is a plugin for Napster. PC World has a short writeup.
Once installed, Napigator 2.0 appears as a tab in one corner of the Napster client. You can click on it to link to a growing list of so-called OpenNap servers. This global network of servers works just like Napster servers, but is maintained by a group of open-source programmers who reverse-engineered the Napster protocol. Using Napigator 2.0 with a Napster client lets you bypass Napster's network and link to an independent one.
The chief advantage of Napigator 2.0 is its ease of use, marrying the Napster client with OpenNap servers. This may draw the millions of people with only basic computer skills and little interest in fussing with other Napster competitors. Many of them are peer-to-peer clients that are more difficult to use, such as Gnutella and Freenet.
And we thought that the sun had just set on Napster
