It's not torrent-like, actually. What it does is provide a web interface to allow you to download files directly to your server from sites like rapidshare.
I've never quite understood what its benefits are, but do have a vague uneasy feeling about its major use being to somehow game the system at rapidshare regarding getting free premium use and waste DH bandwidth in the process (not that I think the OP is doing this).
Anyway remember to be cautious of the PHP memory limit.
