If you're using the STL in your code, then you could add the following...

class cLuaState {
.....
public:
  static cLuaState* GetStateFromLuaState( lua_State *L );
private:
  static std::map< lua_State*, cLuaState* > myStateMap;
};

Then manage creating/deleting entries in myStateMap in your constructor and
desstructors, and write a body for GetStateFromLuaState such that you can
have something like:

int myLuaFunction( lua_State *L ) {
  cLuaState* myStatePtr = cLuaState::GetStateFromLuaState( L );
  .....
}

I know this is terse, but I've not played with the STL in a while, so I
can't easily rattle off the incantations for managing the map :)
