Congratulations on achieving demo status for your project.  This is a game changer for Bitcoin- the greatest innovation in a year since Bitcoin ATM's.  I can't understand why this isn't the top comments thread of the month  -- no comments anywhere yet?.  I think most people here just don't understand what this project is.

Previously I pledged 15 BTC on this thread to you for this- I have just sent you 5BTC and will send another 10 when it has the finishing touches and is publicly realeased.  Please spend this as you see fit (preferably on the project though I don't mind if you spend it otherwise-- you deserve it!).  

I'm interested in knowing if you familiar with the Samsung Knox Android phone- it has very strong privacy and security feature with allow apps to run in secure isolated containers.  Knox would be a great match for this project.  I'll give you another 0.5BTC if you port your software to make use of the available Knox features.  This shouldn't be too hard or take too long, from what I understand you contract Samsung and provided they approve the app they assist in wrapping the Android files to make use of the Knox features.

Have you thought about patenting your split key idea of using both the phone and the card?  It would be a good idea even if you are motivated to introduce this system for the benefit of bitcoin and not so much for your personal gain because it would help your system to become standard.  The widespread use of electronic off-chain private key exchange needs/requires very few solution providers so that people can exchange with others without compatibility issues.

Also how do you plan to advertise/introduce it to the bitcoin community.  I imagine that you could perhaps gain access to users by introducing it to local bitcoin groups and retailers.  This project needs to penetrate where people meet face to face regularly to conduct bitcoin transactions.

By-the-way:  I want this project of yours to succeed, so if it would help it I can lend you interest free up to 20 BTC to be paid back at your leisure as a gentlemen's agreement.  If you would like more I could lend it to you interest free up to 250BTC but this would require a formal agreement (you would have to pay the costs of drawing up a contract).  Even more is possibly available but it would require that I receive benefits in return (eg: exclusive rights to sell in my country, or a part of the business, etc.)
