I think our apps are quite different from yours. We are targeting linux
server systems, and we don't care how big the exes are. I care about
being able to copy a single exe to target systems, and having it run.
Also, I care about not telling the team that builds the installers to
install not just a binary, but a directory tree of .lua files.

You hope, indeed! :-)

Sorry, no, installation involves much more than an binary, which is why
I don't want to complicate my contribution to the problem. Pre and post
lua, if the installation guys don't have to know parts are written in
lua, maybe we can use lua. If they have to know, everybody will have an
opinion on whether using lua is OK.

Thanks, not moving to 5.1 is because of other things than lua socket
(politics), but if we can't link lua socket statically, it will become
technical, not political.
