I do just wana add this bit for you guys.
I'm new to Tekkit but I am a plugin dev for bukkit with quite a few plugins for bukkit.
Mods can not be copyrighted in any way shape or form. They all can be de-compiled for adding and porting over to bukkit, spout etc. I would try it myself, but there are so many lines of code its a little overwhelming bc the dr has a few ppl helping him with his mod. If I can find another dev somewhere that wants to help me I will continue porting and updating the smp version.
