I saw this post that mentions the Performancing for Firefox blog editor plugin. With this plugin, you can post to your blog directly from Firefox.
I installed, this and like the idea, but I am currently going to stick with ecto to do my posting. One problem is that their implementation of the metaWeblog API does not handle categories.
