I hope something good comes out of this, but to me it doesn't look good. In ShadowChat, how is sender anonymity achieved? Just because of I2P, right? I will give them the benefit of the doubt and assume that receiver anonymity works. But sender anonymity is a much harder problem. They're trying to do a lot of different things, and personally I'd rather use one anonymous cryptocurrency, another anonymous communication channel, and yet another anonymous marketplace.
