What can't you control from the C side? I'm not aware of anything you
can't do from C that you can do in script? I prototype in Lua and
optimise back and haven't had any problems yet.

Actually I think you can get locals by setting a functions environment
(read about setfenv()) - I have not verified this - sorry no time.
Search the lua-l archives.

Lua gives you the ability to set up your system how you like. There is
no specific architecture or way of doing things that you need to know. I
know vaguely how VB works and what you are trying to do and you could
set up a system to do this, it's just not done for you. Lua is a pretty
"bare bones", stripped down scripting system, but it is highly
configurable and very flexible, you just have to know how to use it.
Read the Lua tutorial, give it a bit of time and you might find what you
want.
