Proxy script needed for video streaming in php

Hi, I have a .FLV clip website , the .flv files are present on a remote PC - I am looking for a script that can make all the traffic coming on my site to look as its coming from a SINGLE IP to that REMOTE PC- so that REMOTE PC will always see a single IP requesting files. I have a VPS hosting and on the other end its just a pc have all the files on the hard drive. I am looking for a very QUICK and SOLID solution - A bonus and long term opportunities also awaits for the right coder. Thanks and Good Luck !
