Ask HN: How should I open source SimpleAuth.com?

While I'm a big open source user, and I've committed patches to open source projects, I've not yet open sourced a full application.

I launched SimpleAuth.com a while back and there are a bunch of users. I don't mind continuing to pay for the servers as I have SA integrated in many of my own projects as well. That said, I don't have the time to keep up with maintenance & new features that could really make it more widely used (eg iOS SDK).

That brings me to this post. Should I open source SA? If so, how? Or should I just try to find a few individuals that will help maintain/update it without going full-out public git repo?

Of final note, the code isn't pretty, so part of my fear, however irrational, is that while the code works well, the cleanliness of it isn't near my normal standards when I'm not scrambling to get something done.
