I'll chuck my threpence into the ring!
After coding just the creatures from a number of the PFRpg AP bestiaries, a lot of the text from the D20 Magic Item Compendium tome and other data / scripts it really boils down to lack of time / real life commitments and motivation.
It's a generous offer, IMO, for a hobby coder but I wouldn't be able to devote the necessary time to this project either!
