There are a number of free software programs that implement the Gnutella protocol, such as gtk-gnutella, mutella, and gnucleus. Please note, however, that none of these programs are officially GNU software either. GNU has its own peer-to-peer networking program, GNUnet, whose documentation includes a comparison of the protocols.
