RetroShare has been inspired by the design of the Turtle algorithm:

"When designing Turtle, we were inspired by the way people living under oppressive regimes share information deemed "hostile" by their government (this can be books, newsletters, video and audio recordings, or even political jokes). Because of the potentially very serious consequences raising from being caught possessing/distributing such material, no single individual is willing to share it, except with close friends. Experience has repeatedly shown that, even in the most repressive environments, this "friends-to-friends" delivery network is remarkably effective in disseminating information, with relatively little risks for the participating parties; if one chooses his friends carefully, the chance of being caught doing the forbidden exchanges becomes very small."

Retroshare "... makes it difficult to intrude and hardly possible to monitor from an external point of view." This makes government monitoring and prosecution impossible beyond the will of Retroshare users

Free to use.
