DFO is a Desktop Flickr Organizer for Gnome. About itself: "The application allows online/offline mode management of your photos. You can upload, search and download photos, through the easy to use interface." Portage doesn't really have a log of Flickr applications, and this would be a nice addition for the Gnome people. Debian packages at http://packages.debian.net/sid/dfo
Probably mostly useless, but I've started a forum thread about this: http://forums.gentoo.org/viewtopic-t-689229.html
