Omemo is (from their web) "a distributed storage network that is fast, scalable and anonymous, allowing users to not only search-download from it, but also storing their files persistently on this virtual drive, and organizing its contents in folders. Users of omemo will not share files (0’s and 1’s). They will share free space (only 0’s), more accurately, a percentage of their hard drive’s free space. Omemo is a peer-to-peer network that takes all that free space and creates a unique and immense virtual hard drive. Then users can read and write on it, just like they do with their local storage media. "
This project seems a very promising solution for file sharing in a collaborative 3D production.
I have asked for more details about it, like latency, redundancy, etc.
