I do recall seeing the code somewhere in github. I don't mean to discourage you but I think the NetBSD guys haven't found much uses for the Lua module so the justification for working on this would have to find a real use. There was also a suggestion in the NetBSD lists to use Lua for the kernel debugger (ddb) and in their firewall (NPF) but AFAICT those don't really depend on the kernel module. Pedro.
