That's a good idea.  I'll try to cook up a draft.

In the CVS version, we have changed the launch model of luacheia so
that luacheia5.exe is just a tiny launcher app, that sets some
environment variables and calls a standard external lua5.exe with a
bootscript.  So you can replace the supplied lua5.exe with a modified
version, and all the luacheia features should still work.

One of these days we'll package a tarball and binary release...

These are the kinds of things luacheia is meant to standardize; I'll
try to include the key ones in this contemplated LTN draft.
