I am the author of the Google Webfont Loader API module (http://drupal.org/project/google_webfont_loader_api). Before I release a stable version of the module, I wanted to include a GPL font packaged with the project which would serve as an example on how a developer could use their own custom font (or include fonts, or use this font on their own website) to implement on their website. Specifically speaking, I wanted to include Beteckna (http://gnu.ethz.ch/linuks.mine.nu/beteckna/), which is licensed under GNU GPL, in my package. I spoke with Garrick Van Buren (who runs Kernest.com and hosts the font) and he emailed back I am free to do as I see fit regarding packaging of the font with the module. However, I wanted to run it by infrastructure before I go ahead on this matter. I would be happy to provide any other possible information to help my case with including this font in my release package.
