Minuscule changes. I am going to develop a few extensions. I am abandoning the Network controller idea (meaning it is not worth it with the advent of the Sharing, Photos, and Document provider extensions).
Implemented the basics of a Share Extension. It is going to take a while for me to understand how to do it. It seems like I'll need to learn more about grand central dispatch and SLComposeViewControllers.
Basics of the Share Extension done, I really don't have a back end and extensions are designed so that there's not really a way to use Core Data. I'm going to work on the share extension tonight and start on the Documents Provider tomorrow.
