Hi, I'm thinking of running a distributed-processed game. That is, each game simulation will run on an applet on a user's computer and then the result will be uploaded into my data-base. This will save server resources as the game engine will be quite processing intensive.

My main concern is security. Are applets easy to hack and is there any way to create a secure environment? Basically, people could hack the engine and cheat...any ways around this?
