Timo Josten has given us Dropshare 3.3 for the Mac. It's now able to upload files to Rackspace Cloud Files. Also, Dropshare is now able to convert Markdown files to HTML before uploading them.

Dropshare is a menu bar app that enables you to drag and drop files, screenshots and even directories to your own server to share them. For it to work correctly, you have to have a server of your choice and a working SSH user account at your disposal.

Dropshare costs US$4.99 and is available worldwide exclusively through the App Store in the Utilities category. It requires Mac OS X 10.9 or later. Go to http://getdropsha.re for more info.
