Vzaar is a free video player application which you can use to embed videos in your eBay auction listings. It’s an obvious application when you think about it, so should come as no surprise. They’ll need to keep on top of the scalability issues with hosting large numbers of videos, but it’s a decent idea all right. In fact it really sings with some items, like this Eric Clapton guitar. Weird name though, eh (video bazaar?)
