My Next Venture - Help Requested

While reading a very interesting article about RSS feeds and Bit Torrent, I decided that since there was a significant lack of these types of content aggregators I would write my own. Now there is a new twist on a new favorite. I am taking suggestions in the comments section of this post only.

Also, please tell me what you do not want as well, this will help me determine the direction that I will be programming in. Something that I am NOT interested in which programming language you want it in. At this point I am not concerned with that so much as what it'll need to do.
