Nucleus 2

I'm starting to look at doing a Nucleus 2.0 which will be designed around getting online content into the Apple TV

What it will need to do is the following:

  1. Fetch torrents from an RSS feed based on keywords
  2. Download said torrents (should this be multithreaded)
  3. Detect file type of media file and convert video to h.264/mp4
  4. Fix metatags
  5. Import into iTunes

Do you see anything else the app should do? I'm going to yet again do this in python, and probably will not have much in the way of an interface as it should just run as a background task on your computer. Thoughts and comments welcome, is there similar apps already in the wild that I need to know about?
