IC2 crops will probably eventually be supported, it shouldn't take too much effort to modify the existing crops to work with them, but the main issue will probably be the pumpkin/melon textures as they use a totally different texture to the vanilla plants.
Cool, I am looking forward to then. Keep up the awesome work!
You mean the Buildcraft facades based off of Forestry blocks? There's not really much I can do about that as they pull the textures straight from the blocks they are built with, but most of them should work fine.
