LimeWire is a popular peer-to-peer file sharing program using the Gnutella network that supports a wide range of languages and operating systems including Windows, Mac OS X and Linux.
The program features an open community of similar users (defined by interests, computing power, and bandwidth) to optimize search performance. You can run unlimited simultaneous searches for videos, images, documents, programs and audio and your results are displayed via a tabbed interface. A "Browse Host" tool is also useful to find more files that one particular person is sharing.
