You know, I've been talking to a lot of people who run exchanges at these conferences. There's a huge unintended benefit to Darksend. Basically when you mix via Darksend, you're reseting your history. Like clearing your browser history. After the fact when you're sending coins to an exchange from their prospective, address A (your pubkey) is sending address B (their pubkey) coins. What freaks these exchanges out is when it could be multiple people, completely unrelated to your public key that are sending them money (e.g. address A or B or C or D or E sent money to address F). All of these other technologies use something closer to the later, which will cause them to have less adoption in the long run, unless legal compliance gets easier over time... which I doubt.

TLDR; Some decent privacy and an easy to understand blockchain makes compliance easier.
