Brandon, I think that's a wise decision for the short-term, but long-term I really believe this is a feature for core. Paraphrasing Dave, jQuery is all about trying to read your mind. What you've done here is put that notion on steroids. I've been playing around with your plugin and it's really impressive. I can't imagine a more significant and worthwhile addition to core than this behavior code.

Thanks Mike! My vote is to expose the selector and context on the jQuery object as properties and leave this as an "official" plugin ... at least for now.
