Here in the italian mailing list we are discussing about developing the Holy Bible for Beos/Zeta/Haiku, there is someone who want to develop it in English too? Hope don't wasting your time, let me say best regards to you Mattia Tristo
Have you heard of the open source BeLogos? Perhaps your work is largely done. :) (I recall back in the day they had a functional program going...maybe 5 years ago or more now.)
