That would be a neat experiment to see if the conjecture, "Redstone has no means of communication to the outside" is true. It would be interesting to find bugs within the redstone rendering engine that leak or emit data. I'm thinking of something similar to the Super Mario World bank switching pong game.

That would be using a security vulnerability to reprogram the game then, of course if you can do that you can do anything on the computer. Since Minecraft is sandboxed in the JVM that might prove difficult though.
