I think it would be benifishel to the bukit comunity to make this mod :Wolves Extended into a plugin featers: breeding multiple breeds pet gui pet backpack and equitment customer items. mod:http://www.minecraftforum.net/viewtopic.php?f=1032&t=262441&sid=e71fe3c6d2fb6f10db43edec93918f10
The only way to do this was if the developer made a multiplayer version then someone ported it to bukkit. It would also require people to download the mod aswell.
All that piston plugin does is make an iron block into a piston, but it isn't that good. I personally don't like the pistons mod.
