I read much about this project. It seems like really smart people, really good work. They have some weird feeling marketing? I don't know what to think about it, maybe its a "technical people doing marketing" problem? I also don't know how to trust the "shared/cooperative multiparty cryptography" thing? I don't know of anyone else doing the same thing, some underlying feeling I have that it can't really work can it?
