Ok, I have stumbled on a new (new for me remote blog client) that I feel is as good or better than Windows Live Writer.

The latest version supports dasBlog (including images without FTP) it does not use RSD (Really Simple Discovery) but since complete support of dasBlog is built in, that does not matter!

(Note: BlogDesk expects you to have the older 1.8 series dasBlog installed which BlogDesk only supports images with FTP, so re-edit your blog profile and tell it to support direct images and it will, older verions of dasBlog may not work as well, but the current dasBlog build 1.9+ is 100% supported)

This post was made with BlogDesk!

You need to check it out! BlogDesk

Except from site:

"No need to use those annoying HTML Tags in the WYSIWYG editor. Images can be directly inserted and are automatically uploaded. Even publishing simultaneously to multiple blogs is a matter of a click.

With the ImageWizard you can not only insert images to your posts - it's possible to edit them as well (crop, resize, rotate, shadow etc., see Examples). Even Thumbnails can be created - the preview will be shown in the blog and a click on the image will open it in its original size (just like here in the right column). Linking and uploading those images is automatically done by BlogDesk."
