If you want to create an Industrialcraft server using Bukkit for 1.6.2, you need MCPC+ (http://ci.md-5.net/job/MCPC-Plus/)
Just install the mod in the mods folder on both the client and server, and make sure that the client has the same forge version (MCPC+ is currently on forge 871)
""
Check this result (the mod of industrialcraft2 is same in Server/Client):
