Hiding FLV Source of embedded videos

i have many personal flvs, i want to embed them on my website using the JW plugin, [login to view URL] I don't want the flv source to be shown, I need a plugin to hide the flvs, or make it unable for other people to leech it. I guess the script would be something similar to http://www.freelancer.com/projects/PHP-Website-Security/HIDE-URL-SOURCE-PROXY-SERER.html My personal flvs are hosted on another server, I need this script to be a wordpress plugin. Can anyone do this ?
