I'll give it a shot... If you download any of the new adobe program trials off their site I have serials for all but flash... CS4, CS4 extended, Indesign and Dreamweaver etc.
I had cs4 but could find it, plus the trial expired so I just uninstalled it. you could probably put the zip file for ps in a folder on your site....then if I knew the file name/folder... i think I could get it by url.. rpmmagazine.com/phragle.zip would dl it I believe...
