Thanks, for your support!
I don't deny that the work will be difficult to complete, and as the clock ticks down with our proposal under the funding threshold it will become harder. We had planned to hire more people after the funding was secured, especially in regards to the game and app. That may have to wait a little longer now, but it's still being considered.
About the SDK and Services: I plan on taking a 80/20 approach when prioritizing features so if a few things are left after the funding round is over the project should be far enough along to support most developers. I've also worked on several projects with similar goals (just using different methodology) in the past so we're not starting from scratch intellectually which should lesson the time required for each feature.
Unfortunately we may have to revisit the proposal as time goes on and remove some of the stretch goals or at least extend the timeline of release if funding doesn't materialize, but hopefully it wont come to that.
