Congrats! And will you be doing a final wrap up blog post about the process? If so, I am looking forward to it.
I'm also in talks with Twilio about producing something with them about it. Preview of coming attractions: everybody should use Twilio. Oh goodness. It is freaking amazing. It is like email: add it to an application, just about any application, and it gets suddenly, radically better. (And the existence of it makes possible applications that wouldn't be possible otherwise, like AR.)
Now I just need to think of something to make that can take full advantage of their capabilities.
