How to teleport players in random directions in Minecraft?

I was making a minecraft custom map and i need a way to teleport players in random directions. If anyone knows of a way i could do that it would really help. Also if there's a way to teleport them in a random direction within a certain area i would really appreciate it.

You're going to have to make it a server and add plugins to it in order to teleport. Try bukkit.com for making the server. And the teleportation plugin will be in the essentials package
