It was no a simple decision, I really enjoyed the dynamic approach. I thought about keeping the font as is and writing some python glue code to convert it a build time to the "static" form, but I dismissed it because it was impractical given the level of complexity and the time available to me. However the dynamic structure still more or less intact though bypassed. The problem is that most bugs involved proprietary systems, HarfBuzz (the most widely used free OpenType implementations) was the least buggy one and had almost all features I needed, if I were to target only free software life would have been much simpler!

You can follow me @KhaledGhetas on twitter (I'm late to micro-blogging; post revolution), I guess it should link to it somewhere here.
