I've downloaded the code and am looking around it. So far it seems pretty clean. This is not the type of development i'm use to doing (i do more enterprise type stuff, so a lot of database, console apps, websites, windows services). Plus, my company is stuck using tech and practices that are about 8 years old, so one of the things I'm looking to get out of this is using more modern stuff like IoC, Json, which you are already using.
Sending you a PM now...
