I notice that Bible Gateway is pretty footnote/commentary light… even on Bibles which (if I recall correctly) require that their notes be reprinted with every reproduction of the Biblical text 
I bring this up because one of the big reasons I wanted to do this was because my gigantic study bible is just too big to read away from a desk and I wanted to read some Bibles with heavy commentary (particularly the NRSV w/ Apocrypha) but if I recall correctly from the other thread, the process requires turning footnotes off? Is there another Bible site to which this can be applied? I’d still like to read the Louis Segond (might help my French) but really… some way of turning an ebook into markdown might be easiest, because I think I have ebook versions of one of my bibles. I’ll have to check.
