I will Open Source it at some point, I can't really spend any more time on it, for the next 2 weeks, as it is I should't have spent any time on it at all. I would like to submit it to the AppStore but I haven't got the money (hence it being on dropbox) :)

@George, ah thanks for reminding me about that. I thought the spec was on the private beta announcement, I forgot it was "draft".

If there's anything I give you (url, response etc) to help, just say.
