iControlU?

Okay, so I read a post that somebody wants iCU, so I started porting it to MCPE, but then I remembered that VanishedKevin had an iCU in PocketEssentials, so now I am asking if I would get banned if I posted MY iCU?

No because you are not using his code you have your own. Plus he got banned for other reasons...

But you may be banned if you use his code, just make sure to write your own code

I don't think anybody should be reproducing it. If you go to the Bukkit plugin at http://dev.bukkit.org/bukkit-plugins/icontrolu/ and look at the license, it says reproduction isn't allowed.

This dude's the author. Ask him if you can.

I think it is not a reproduction. He just licensed the software, not the idea of iCU. If he wants to patent the idea of iCU, I think he has to go through procedures like what scientists do for their inventions.

If you just write "Copyright by ......" then it won't count in a lawsuit. You need to officially register your product/code.
But every person with a bit of respect don't copy someone else his code.

But a bit of respect doesn't make this idea of his be monopoly. And I don't think pocketmine plugins won't affect him at all.
