Exactly, the hammer is slowly closing in, first Shapeshift and not EtherDelta, but the sad news is that its only the American crypto enthusiast will be affected isn't it? I also forget that even one of the hated exchanges, HitBTC are requiring KYC now so probably we will see DEX platform slowly succumbing to the pressures of government bodies. So it doesn't matter at this point if they have a case or not, remember its US and we all know the power they can wield. (BTC-e is one example).
