Client connect to BTProxy, giving it the .torrent file.  The BTProxy Does all 
the bit torrent stuff, downloading fragments, and sharing them with other BT 
clients. The BTProxy returns the final file to the Client using a simple 
protocol (FTP?) and it gets saved locally.  I can even shut down the client, 
and the BTProxy can continue to share fragments with other BT clients.
