I think without launching with a myriad of SDKs and libs isn't the smartest idea. People want to be able to get up and play and not wait for a product.

I get the idea about judging demand and stuff like that, but if I wanted to integrate this into something, I sure as hell wouldn't want to have to write my own SDK for it, especially since it's a new service that I don't know will last. Launching without my code in mind means that someone isn't as dedicated to their product as I might be. That's scary.

I kindly suggest a repost in a month with the title, "Show HN: Hoomi Libraries, a New Single Sign-On Service for x, y, z, a, b, c, d, e, f, g, h, ... w."
