Thanks for your comments tomkat and thanks for checking out our project.  We do value feedback and we do think it is wise to carefully plan Sonajin and our apologies if it wasn't  more clear in the initial 2 years of research and planning in the road map.  The reason feedback is so valuable is for the long-term success of a coin which we feel is going to be marked by trust and community involvement.  Part of that aspect is incorporating as much of the community's feedback as possible into our vision for revolutionizing cryptocurrency.

You are also correct about the OpenSource aspect.  The wallets will be OpenSource but as we mentioned, our hybrid-proprietary blockchain can only be fully secured against attacks by not allowing strangers to run nodes.  If there does become a way in the future to make the node side OpenSource we would be glad to do it, as this would reduce our task of managing so much hardware and computing power on the backend side.  The downside to public nodes is inherent increased risk and overall decreased transaction capability.  However, we see a long-term benefit for the user side as everyone can focus on using Sonajin to buy and sell products and services without worrying about the traditional problems with other currencies.
