Own World for Each Player

Is it possible to make a plugin where each player has his own world. And the player can invite players, ignore players,allow/disallow to build for players, and so on or does this plugin already exist?
Thank You for your help.

 

That's a LOT of worlds, especially for a large community... o:

 

This would cause SUPER LAG in ur server...

 

Well, that's a idea close to mine....My idea was a little plot of land for everyone, like a private home, where noone can grief it.

Maybe space people out in the "End"?

 

I might concider doing this, but you are going to have to make this like a donator perk, becuase even if you have 20 worlds, it's going to make your server explode .
