I have been looking for ways to easily embed models in web pages, and this service offers such an ability. You can check out the beholder chassis (whoops, missing the gun texture) here http://sketchfab.com/show/zqTAKg67NuSSR5idVSSnLRgYlzf
The display is brisk and responsive in your webgl compatible browser. I haven't tried to embed models, but will soon. They take a good range of models, this one is an obj file export from a Misfit file. They take all the big boys too, Max, Maya, Blender. Worth a look.
