Operation of the maidsafe system as advertised relies on a number of provably impossible technologies, like purely algorithmic proof-of-identity.
They gave a presentation at a recent Bitcoin conference in DC. I asked a few basic questions about how they planned to do certain things critical to maidsafe's operation (that no one knows how to do, and many think are impossible), and their answers were so obscenely stupid that anyone in the room with relevant technical knowledge was laughing.
Example: "How do you plan to prevent bots from gaming the data transfer payment system?" The answer was something like "Oh, it's way too hard to make a bot. There are too many steps."
