Yes, we know the DarkSend test is soon, but when people ask when it will be, they already know it is soon, so saying 'soon' isn't really any kind of answer! :/ Throw us a bone with numbers written on it, if you catch my drift.

I don't have a date, but I'm guessing in 2-3 more tests I'll allow people to start using DarkSend on the mainnet using the ubuntu/windows binaries. There's really no risk to using it and it should be stable in a couple weeks.
The problem is to opensource it I need to do a fair amount of work to secure the way it works and make sure it's very robust in dealing with possible errors/issues. But I can start to work on that while you all are using it on mainnet.
