This is a bad description of what the project is about. I've been working with the Mastercoin people and have met the Maidsafe people at a Hackathon and they're doing some really neat research.

Basically they're creating a service that lets you monitize your unused resources such as unused hard drive space or CPU cycles.

This has been tried before and it'll be tried again; I can't see it happening anytime soon on a large enough scale for it to become popular among a large amount of users.
