Vogging

Vlogs/vogs, syndicating video feeds, which will work well with iChat on Mac platform. The Sony game machine might become a cross-over product.

Use Ant as video-reader. Look for a tag and drag and drop tag into aggregator or blog reader.
Screencasting, as in screen movie is great to cast.

I have one problem with iSight. You can't podcast with it. The iSight hardware is great for creating video, but what a mistake it is to not make the microphone capacity of iSight to be useable for podcasting work. Currently the mike function only works for videoconferencing. I wonder how that came about.
