"OceanStore is a global persistent data store designed to scale to billions of users. It provides a consistent, highly-available, and durable storage utility atop an infrastructure comprised of untrusted servers.
Any computer can join the infrastructure, contributing storage or providing local user access in exchange for economic compensation. Users need only subscribe to a single OceanStore service provider, although they may consume storage and bandwidth from many different providers. The providers automatically buy and sell capacity and coverage among themselves, transparently to the users. The utility model thus combines the resources from federated systems to provide a quality of service higher than that achievable by any single company. "

Yes, this project doesn’t seem to be active. However, it appears to have proposed/offered very very similar ideas/concepts to SAFE. In some literature I found it describes a byzantine consensus mechanism, ACLs, version control, dynamic replication, immutable perpetual data archives, and erasure codes. Very interesting. Maybe there are some implementation ideas there that could benefit maidsafe devs if they haven’t already heard of it before.
EDIT: It appears that this project may have been deprecated in favor of BOINC.
They also had an article in scientific american promoting a world computer. One that is maintenance free and autonomous.
These references provide a lot of information
