Yes, Snark! Security files are not the only good thing about Shareaza. It is an excellent Gnutella client overall with a slick interface and loads of features. So far it has been 100 % stable for me and also easy on resources - some good p2p programming there!
Support for superpeers, content hashing, metadata and multisourced downloads have all taken Gnutella protocol greatly forward, and with clients like Shareaza the future of Gnutella looks bright.
