Lightroom Publish Service
Would be nice to have Lightroom Publish Service (Lightroom plugin).
This feature has been released
For now, you can set up FTP to upload directly from Lightroom to BlueMelon. You have to use an external plugin, but the plugin is already well tested and widely used. Here is the link to all the settings: http://support.bluemelon.com/customer/portal/articles/835910-upload-from-adobe-lightroom
