Videora is like podcasting for video, using Bit-Torrent. Om just interviewed the creator of it. What I think is neat is it works without needing a special element (like <enclosure>) in the RSS, which incidentally means it works with non-RSS2.0 syndication formats as well. It doesn’t need any new formats, and works today. This is how I think other aggregators that support rich media will evolve, it’s podcasting without the hassle on the publisher end.
