Me and Ape spent the last couple nights defeating various bugs with the implementation. We're making huge progress to a closed alpha, there's a couple more things I want to work out, then we should be able to release something (maybe this weekend if we're lucky?  )

Ps, As for naming things, I think I'm going with DarkSend. It works well in all of the different ways it needs to "Darkcoin with DarkSend", "./darkcoind darksend Xaddr 10", "Just darksend the money", "The darksend is still pending", "To see the status of the DarkSend Pool, just type getpoolinfo", and all of the classes will sound cool (DarkSend, DarkSendPool, DarkSendInfo).
