MITN: One last plugin idea.

I'm moving away from plugin development and towards my own game development, but I have one last plugin idea to create.

Description:

I'm going to try and describe this as best as I can. Do you and one (or more) friends own a minecraft server? How would you like to send stuff or trade stuff to your friend's other server? I introduce to you, MITN. (Minecraft Inter-server Trade Network)

The MITN will be able to connect to other servers who have this plugin installed. Of course, only the people you allow to trade with your server can do this. This plugin was in inspiration of NAFTA (North American Free Trade Agreement) which prevents blocked trade between all North American Countries and Provinces.

This plugin will be able to ship, or send, any item to the requested server. Therefore you could probably have your items on multiple servers. But this plugin will prevent that by making sure the same player isn't logged in on that server during the time of the trading.

This plugin will assuage the difficulty of trading items with other servers if they do not wish to have the hassle of transferring files through ftp. (or ssh, whatever you use)

The Challenge

I have been studying the art of cryptography and how SSL (Server Socket Layer) works. I am planning on using sockets to do this, but the challenge is making it safe and secure without losing that light weight lust. Therefore I will explain to you my plan.

OpenSSL uses a key to unlock encrypted data. I will be using the same method to facilitate security between servers. Why? Hackers can modify traveling information. If your players are wise and knowledgeable in hacking, then they could possibly change the data to something they want to recieve. Take for example, the player sends a stone sword over to another server. If he could, he may have the skills to modify the passing data to a diamond sword with maybe OP enchantments - as you commoners may call something too strong. This is why it is important to secure the data.

If you think this is a prestige idea, then I would like your feedback.
