Just after the fork of Inkscape SVN-0.46 & SVN-0.47, the support for advanced SVG fonts management (already supported by Fontforge) was started. It’s also good to recall than a SVG print draft is in progress, and everyone is welcome to improve it.
Fontmatrix is a nice font manager with lot of informations about fonts, last SVN launched from a terminal, give font path and filename on the terminal (soon on the interface ;) ). It allow to activate/disactivate fonts in the fontconfig system for GNU/Linux.
Some other free software font tools and converter on the Fontforge project page.
