I am afraid even though a early supporter of XLB that was one of the first on irc , X11 Coin or XC have already done the POS-Anon wallet and have released a beta version today to the public.
I have personally tested it and it works even though dev mentions using small amounts just in cause until the end of the week when a 100% official version releases.
https://bitcointalk.org/index.php?topic=600706.msg6942073#msg6942073 Compiling the last build of the night... I will be uploading shortly. The good news is that the features outlined in the visio are fully implemented and 100% functional as designed. The bad news is I'm exhausted and was not able to update the QT side so you will need to use the console via the debug option on this windows release.
the command is
sendfrommixer <# of XC>
so example
sendfrommixer "" 1
if you have multiple accounts with labels, put the label inside ""
Limit your transactions to 1 XC or less for this current phase
This is beta software, please exercise caution
