I'd like to know, too.

One suggestion - Could an option for the script be to "read from a source file?" ie: Just a button that will prompt you for a text/data file location and that will read that file in order to reproduce the settings. And, the reason for that is so that people can easily share their settings with others. Of course, they'd have to also either share or point to the download location of the IBL image, but that's simple enough, too.
