I suspect with the release of the
iPhone folks will start to share Video Content much more readily and EFFECTIVELY than ever before. So I'd say we're gonna see major changes in this errr..

You only need to look at Podcast & Global Music Sharing trends before and AFTER the release of the iPod to get a pretty good indication of this burgeoning phenomena.
