http://voices.yahoo.com/siddley-inc-unveils-anonymous-digital-currency-7420634.html This has been in development for several years and I hear that Pecunix is about to start using it. This is certainly going to be the model that is the future of traditional, gold backed E-currency systems. Should offer bitcoin significant competition too, considering it actually has strong anonymity built into it and also is backed by gold so wont have price fluctuations. I wonder if they can resist government trying to shut them down, I am kind of amazed Pecunix in its current state has not been shut down to be honest, but they seem to know all the legal loopholes required to not technically break any laws.
