 Hoarder
 ========
+Uploads .torrent files from a local "blackhole" to a remote (SSH) rtorrent watch folder. From there, rtorrent is polled over XMLRPC as to whether the torrent is completed. Finally, the files are downloaded over a multithreaded SSH connection and saved to the local machine. The blackhole is used as a queue and will have its .torrent files deleted.
