What's new about this? I think I'm missing something for this submission.
I don't know if there's anything new about it, but I have not seen disk encryption with plausible deniability before. From my point of this, this is new. This should be (could be) an important building block of anonymizing projects like Tor and Tonika.
I just sort of think it's fairly well known around here, but I could be wrong.
I don't think there's anything new, but it's a fantastic product.
