Auto Uploader for an private tracker

We need an Autouploader for a private torrent tracker, we got some requirements for it 1. a safety so it only can be used at our site, and if the user stops as uploader we need a method to shut down his program so he cant use it anymore, we thought about looking it to the 32bit passkey all users have. The program should have our different categories so the user can select which category they want the torrent uploaded too It should function this way: 1. Make Torrent. 2. Copy/paste the .nfo to the description. 3. Upload torrent 4. Start Seed We also need to have a way to log which users are using our script.. The staff at the site probably have many more ideas and would like to talk with our freelancer. I would like to apologize for the bad english grammar, im danish so its a little hard :)
