Regarding Samsung Knox, it already works with it. I've actually had Samsung wrap OtherCoin + the official Android Bitcoin Client + the helper tools for the Bluetooth OtherCoin and they all run from within the Knox container (tested on a Galaxy Note 2). The problem comes when interfacing with the OtherCoin card - Knox containers disallow communication to external storage (so no microSD or USB) and also block NFC. Only Bluetooth should work, but it doesn't (there's an exception in the BluetoothSocket system class - not in my code). I'm all over Samsung's support for this, they have specifically told me that Bluetooth should work but now they claim that only very specific "whitelisted" Bluetooth smartcard readers are allowed. But yes, it works in Knox, if you have a Samsung device that supports it let me know and I'll email you the wrapped APKs to try it.

Yes, I should have realised that Knox wouldn't allow communication to external storage such as the SD card. But good to see that you've wrapped the parts anyway-- I am sending you 0.5BTC for that.

Depending on how much we raise from early regional resellers, I might take those 20 BTC you've offered as a loan, I really appreciate the offer. Thank you!

(we should probably move the discussion to the Project Development area sometime, right now it's a mix of tech + project dev)

Anytime you wish to take my up on the offer just post a message here or in the other thread (which I've just discovered) about this project in the Project Development area and I'll send it to you.

PS: regarding buying distribution rights. For me personally I would require that you have some sort of patent protection so that other competitors couldn't steal the market with alternative products. Unfortunately, the basic concept of off-chain electronic transactions by secure private key exchange would most likely not be patentable since the mechanism has been publicly detailed previously by others. However, your idea of splitting the private key across the phone and card offering further customer protection I believe is novel (not only novel but also a great idea too

) and should be patentable. The split key feature could provide a selling edge to establish your product in a market dominating position-- a dominating position in this market is golden due to the fact that it has a native lock-in factor owing to the compatibility issue surrounding the cards being able to talk to each other and establishing secure connections.

(Actually, as-an-aside: In my particular case of Australia it may even be the case that you cannot patent the split key idea as it is my understanding that our law requires that the idea never be published before the patent application-- however I think this is the exception of most countries than the rule. I believe that in places such as the USA you have up to one year after publicly detailing the mechanism to patent it-- but I'm not a lawyer so not so sure.)
