My favorites so far are Sarah McLachlan’s “World on Fire” and an Aikido training video. I like this idea: using Bit Torrent, the nonprofit Participatory Culture Foundation helps publishers distribute their content inexpensively.

I would like to see more Indy SciFi movies and TV shows, and Bit Torrent distribution with embedded advertisements would greatly reduce costs over traditional broadcasting.
