From the quick look I took at zipping and permissions, it doesn't look like that's possible. From the link I found "As far as I know the permission system in Linux is set up in such a way to prevent exactly what you are trying to accomplish." I'd assume it's an intended Linux security measure. I've added a section for Linux in the download notes that mentions the need for giving the executables execute permissions alongside the other things you mentioned, thanks for the notes, as you can probably tell, I know very little about Linux.
