We use tolua for the interfacing of lua<->c++.
For registering objects created in c++ to lua we use the following small
code snippet:

void CUtlLua::SetGlobal(const char *_sVarName, void *_pData, const char
    lua_pushusertag(pLuaState, _pData, tolua_tag(pLuaState, _sTagName));
    lua_setglobal(pLuaState, _sVarName);

The same method would probably be applied to other wrapper systems. The key
to the solution is to assign the object pointer the correct tag.

Subject: C++ creation of object, and Lua co-calling

For my game scripting, I need to be able to expose methods from objects
created in my c++ class to Lua.

I know there are a number of solutions for providing c++ classes in lua so
long as they are created in Lua, but what about when the construction is in
the host application?

Essentially, I need method sharing with the creation process being
consumated by the c++ app.

What is the simplest, and least ambitious method for doing this that you
experts can think of?
