Hi Damien,
I don't know of any way to do what you are asking in Moodle, but I can suggest a possible way. eXe is a free program that lets you make a course/package like you need and export it as a common cartridge, scorm 1.2 zip, IMS content package, a web site, or a couple more options. I have used the web site option myself to do exactly what you want to do.
The web site export option can be a self-contained folder or a zip file. I use the self-contained folder option myself.
In fact, eXe and the self-contained web site is the way I have students create a portfolio of all the applications projects they have created for me this year. It can be placed on a CD or USB drive and students only need to know how to get to the index.html file. eXe has lots of capability as to the types of pages you can make.
Hope this helps,
AL
