This is a great idea but on first glance I'm confused how this ties in with the messaging and reservation/order placement system on the main site. It seems you can just watch a video but then you have to separately go to the main site and again search for that listing in order to place a reservation for it. The other question I had about this is how costly is it to host your own video? Or are they riding on top of some external video hosting service? At the moment it seems Airbnb cherry picks the properties they want to promote with video - they don't allow regular users to upload videos of their properties to augment the images that they can already upload. Why not simply allow everyone to upload videos? Is this a cost issue? Because the current implementation creates an impression of unfairness - why promote only some properties and not others?
