Video casting support in iTunes

I found this link today at AppleInsider that demonstrates a "Vodcasting" feed that an industrious user has set up. Pair iTunes 4.9's video playback capabilities with an RSS implementation that syndicates almost any valid RSS feed, and you've got a vodcast waiting to happen.

Users of iTunes 4.9 can subscribe to this feed as a podcast. I did, and it all worked just as it's supposed to. However, instead of loading a podcast into iTunes, the feed grabbed a video. Pretty cool.

Does this give credence to a potential video pod? Could music videos and/or movie trailers (both of which already exist in the iTunes Music Store) be distributed this way? I can certainly see the potential.
