The file-sharing landscape is slowly adjusting in response to the continued push for more anti-piracy tools, the final Pirate Bay verdict, and the raids and arrests in the Megaupload case. Faced with uncertainty and drastic changes at file-sharing sites, many users are searching for secure, private and uncensored file-sharing clients. Despite the image its name suggests, RetroShare is one such future-proof client.

It sounds like a pretty good program.

^it is actually optional now that I use it. You can share files, and download them without others knowing but you can also.. share such information.
