Cross-Posting to LiveJournal (**including external editors**)?!

Is there a way to automatically crosspost to LiveJournal, <I>including anything that gets posted via external factors such as external editors, the ‘blog this’ button of Flickr, or other manner of beastie</I>?

I know of LivePress … but, correct me if I’m wrong, it only catches things at the post-from-the-Web level, which is not the way I normally interact with my blog.
