I have a quick question for you, having just browsed a bit of the GitHub repo. Are you using the Nymi SDK? Do you know what the licensing terms for it are? How redistribution of it works? I can't seem to find any info on their website....
Thanks.
The NyMi SDK is free to use as far as I know. You just have to register as a developer and use it. They have an emulator that is available that you can use.
Hope that helps.
