MovieLoader.loadClip() includes an onLoadProgress handler that allows to 
do what I was trying to.

To include the load_text variable that was inside the onLoadProgress 
handler, I had to rename it to _root.load_text (new script below, 
http://www.archive.org/download/Lessig-Free_Culture/lessig-freeculture-loader.swf).

But I still have an issue with this loader. All getBytesLoaded and 
getBytesTotal are counted with uncompressed sizes and since the actual 
file is compressed, these size numbers are wrong. Is there any way to 
get the actual compressed bytes with getBytesLoaded?

Thanks for your help,


Pablo
