Mob World

Im not sure how much of a hassle this would be but I think it would be a good idea to have a small separate world that was always day, only about 500 by 500 blocks, had PvP off, only spawned pigs, cows, sheep, chickens, squid, and wolves, and had no buildings, save for the spawn. This would just be for collecting food, wool, and ink sacks. The main reason i am putting this out here is because there are far to many mobs that nobody can get to in the main worlds, and they take up a mob spot. Even worse is that they don't despawn! To make this reasonable i also think there should be a price to port to this world. Tell me what you think! ;D

 

It's been suggested before, but this would cause a lot of lag.

 

I have seen other server with this one that some old shadecrest people play on had a Halloween world with a crap load of mobs and it have zero lag and that server dosent have as good of a host as we do so it might work.
