Blog API and blogging tools

After reading George's solicitation, I decided to take a look around for win32 offline blogging apps. The two I looked at this morning (w.bloggar and SharpMT) didn't work with my old 'zlog, which is a bit annoying. From what I could see, w.bloggar uses methods not supported by s9y and SharpMT is broken (the correct responses were being sent, it just kept thinking that there was an HTTP violation).

Is there good, bloat-free (or at least, not over bloated) app for win32? Is there one for linux ?
