Available starting in 2003 for iTunes 4.1, OurTunes was an open-source Java-based utility for listening to other people's iTunes libraries on the same local network. The problem, but also the fun, was that it was a utility for copying files from those libraries as well. iTunes 7, released in 2006, changed its authentication scheme and broke OurTunes. iTunes has long permitted streaming music from shared libraries, and version 9 added the ability for a limited number of computers on a sub-network to copy each other's files. But the "free for all" nature of OurTunes has not been duplicated -- and isn't likely to be.
