Cabos is Gnutella file sharing program based on LimeWire and Acquisition. It is free software, no spyware, no adware. It provides simple interface, multi languages support, and iTunes / iPod integration
I haven’t used a P2P (file sharing) application in some time now, but I must admit this one is especially nice for music. Purely 100% totally legal music, *cough*. Definitely worth a look. Clean, easy to use, and quite fast.
