I've heard of Tahoe-LAFS before, I am under the impression it's for when I own the storage server rather than using a network of other peoples server? My dream is of a network of other people operating the servers for both liability reasons and it would be cheaper because given a network of people paying with bitcoin, it would be oversold, reducing the price more than getting a dedicated server (assuming there is competition). If I'm wrong, and other people provide storage with Tahoe-LAFS, how are you recieving money for it? Storage is expensive when done on enterprise scale, we can't rely on peoples open internet idiology for something as expensive as that.
