Quote from Oswarlan
why would it be? millenaire (spelling?) and ic2's recipes show up... unless you mean how RP2 uses meta-data for almost every item, in which case it would probably still be possible, although with more work
On the off note, RP2 (and other mods are moving to this as well) *does* use meta-data for almost every item, including smeltables.
Also, when you do add SMP support then would it be possible to add a configurable lifespan for the book, so it can only be opened so many times before it vanishes and they have to remake it?
