The question of whether AFDKO is a free software project is unclear. Even just downloading AFDKO from Adobe requires first accepting a EULA: http://www.adobe.com/devnet/opentype/afdko.html There is a github project with some code in it, but it's not clear to me whether it can be built and made functional without using non-free development tools.

This will require more investigation. Thanks, Mark

I was assuming that font editors typically operated directly on font files, so there is no corresponding source. I guess that's not true though, since FontForge operates on SFD files and Adobe apparently works with AFDKO files. The question is do we need to built fonts from source? I think we can package Source Code Pro either way. It looks like there are two versions of AFDKO, a free software version on GitHub [1] and one with non-free code on adobe.com.
