Here's a largely hacked about version of Feed On Feeds (based on the latest version 1.9) that I use for reading high-volume feeds such as from torrent sites. It has a number of handy features, so I'm making it available in the hope that someone else might find it useful. Feed On Feeds is GPL licensed, so hopefully it's ok to distribute this here.
Installation instructions are the same as for the original - basically just create a MySQL database (or use an existing one), edit config.php with your database connection details, upload all the files, run install.php, then add some feeds (for connecting to private feeds it's user:firstname.lastname@example.org/blah) and set cron to run the update script every 30 minutes or so. See the included README file for a few more details.
