A new article over at TorrentFreak indicates, once again, that free downloads and 'for-sale' distribution model might well co-exist, even if it's much too early to tell if this model is doing to be stable. They write:

Mininova, one of the largest BitTorrent sites on the Internet, will launch a new feature today that will help artists, labels and other content producers to generate revenue. The Dutch record label ‘Beep! Beep!’ is one of the first to try the new feature, which allows content producers to add ’shopping links’ to their free torrents.
