You have to download SWFObject from http://code.google.com/p/swfobject/
too, and add the files swfobject.js, expressInstall.swf next to the
AutoInstallShockwaveComponent.java to have it work
any feedback will be appreciated. I didn't try to add several
autoinstall to a page, so if you try, let me know if it works
;)

Hi Sébastien!
I am interested! Could you post the code/markup?
Thanks a lot for sharing,
