For this to work, you can't use os threads, the scripts must be run alternately in a single os thread.

First thought is to run the two bits of code in two separate threads in the same state. If not I would look into LuaProxy. It lets you access variables in one state through a userdata in another. The userdata acts like the global table of the other state I think.

I don't know if it's possible, but you might be able to use it so that each state can access the other one, or both can access the same 3rd state with your table in.

Thanks,
