I've actually implemented some functions that can copy nearly any value between Lua states: http://pastie.org/8996668

Hi,

When you copy Lua functions, you should also take care of their upvalues else they won't work as expected (if at all) in the destination state.

You may want to have a look at lanes, which supports inter-state data copying.

If anyone's using this code, here's a bug fix you'll want to apply:

    if(luaL_getmetafield(from, pos, "__xcopy")) { //-1: func


    lua_pushvalue(from, pos); //-1: obj, -2: func
    lua_pushlightuserdata(from, to); //-1: to, -2: obj, -3: func
  - lua_call(from, 2, 0); //-1: result
  + lua_call(from, 2, 1); //-1: result
    int res = lua_toboolean(from, -1);


    lua_pop(from, 1); //remove result
    return res;
