Video Download Script

I'm looking for a coder to essentially recreate a piece of software: phpscan[dot].com It should essentially do the same thing. Download videos from YouTube and other sources. One thing I request is that it has a built in key type system. If the software is made public, I want to be able to eliminate that key from use and have the script no longer work. It should be as secure as possible. ## Deliverables Please make notes for any special installations needed for the script to work on my web server if possible.
