I hope too that once the SDK is released you could do everything directly and officially and either Fbreader will be ported or Books.app improved
I remember something about future Books.app improvements. I think that the lead developer said on Teleread that he was considering adding epub support.
If someone could use Safari to take care of the HTML+CSS and work on supporting metadata/TOC, it should be possible to create a very good epub reader on the iPhone.
