A mapping mashup, great virtual tours

Another day, another mash-up. This one is pretty cool. Mapwing.com is a little service that allows you to mash-up photos, placed or drawn maps, and comments to build interactive virtual tours. Damn, this could be the right mash-up that someone like Zillow could incorporate into their real estate service. Mapwing has a gallery of some really cool tours, which can also be emailed or embedded in blogs.
