Chitlesh Goorah has announced other Fedora planetary systems that include Fedora EL, Fedora KDE, Fedora BrOffice, Fedora Edu/Math, Fedora AOS, Fedora XFCE, and Fedora Developer. Fedora EL is the Electronics Lab edition of Fedora that includes free software for circuit, component, and modeling design. The Fedora KDE and Xfce spins are similar to Kubuntu and Xubuntu for Ubuntu in that they just drop in a different desktop environment.
Fedora BrOffice is a Linux office suite that caters to the Brazilian Portuguese population. Fedora Edu/Math is for the educational crowd and it ships with a variety of mathematics and scientific applications. The Fedora Developer spin is a LiveDVD that provides various IDEs, access to multiple revision control systems, GCC, and other build utilities and libraries. Lastly, there is Fedora AOS. Fedora AOS allows end-users and developers to build pre-installed, pre-configured, system images that is essentially Red Hat's equivalent to Ubuntu JeOS (Just enough Operating System). Fedora AOS is part of the Appliance Tools feature.
More information on the different flavors of Fedora is available from the SIG Wiki. The spins are available for download via Bit Torrent from this page. Due to multiple architectures, there are actually twelve spins in total that are based upon Fedora 10. This is quite an increase compared to Fedora 9 that just had four. Of course, if you don't want to download a separate spin to get a few new programs, all of the packages that make up these spins should be available through the default repository once installing Fedora 10.
