Blog Torrent is a way to offer large files on your website without using any storage or bandwidth.
UPDATED: You really should check this software out. Erik and I both downloaded and installed it and had our own BitTorrent trackers/servers going on our sites within 5 minutes. I’ve uploaded a couple BeerCasts and couple Mobius Mixdown’s there… enjoy. If you get it installed and upload some stuff, drop a note in the comments with the URL.
