I underestimated the scope of this project and set too ambitious of a schedule for it. Zerocoin will be probably be ready within 2-3 months, but I don't want to give any more release dates (either for testnet or mainnet) until I am very, very close. I will not make this mistake again.

I will continue to give status updates, and I have made tremendous progress in recent weeks. As I promised, I will still work full time on this until November 1, and I expect to have a few hours a day after that to work on it.
