MP3SQL allows one to index MP3's with MP3Tags into an SQL databse such as MySQL. Also included is an example PHP3 script for searching the database. There is also an playlist add function and an great playscript that reads your playlist and if there is no entries it randomizes from all your mp3s.
napMan is an infobot that provides you with a real time glimpse into the current state of the worldwide network of nap servers that are based on either the closed source Napster protocol or the Open Source opennap protocol. It displays a list of all the nap servers and current statistics for each server (users, number of MP3 files, gigabytes), and provides the ability to ping individual servers and check the network lag time, a facility to save the list of servers and statistics to a file, and the ability to refresh statistics for individual servers or all the servers.
