Hacker News iPhone App

I am an experienced iPhone developer interested in creating an iPhone app for HN, similar to iReddit. However, there doesn't seem to be an API nor a way to access any of the data, other than through an RSS feed. I want to tightly integrate and include the ability to login, post comments and obviously upvote/downvote stories.

I read from the comments that the guys from 280North are working on it... Any idea how they're getting the data and talking to HN?

I would most likely make anything I make open source and freely available on the AppStore. I love this community.

Thanks.
