Contest: Get Out Of The Lua Sandbox

I have a challenge:
Escape the lua VM/sandbox and allow access of the underlying Java code running MC and CC using nothing but rednet and normal CC lua
Have fun escaping the lua VM/sandbox

Well, I don't think that's possible. Not to a point where you can run Java code for sure, and you won't be able to run any "special" Lua code either. The only hack that was available to us was the string metatable and string function environments hack, which is now fixed.

If this was still possible, there's no way anyone could prove it to you, because I'm pretty sure it would count as malicious content, and therefore they wouldn't be able to share the code here on the forums.

And that about sums this one up.
