Clara.IO enables you to do 3D modeling in your browser. It's growing into a full fledged 3D software package. This script helps you upload your 3D models to Clara.IO and to download them. Current version supports vrmat export which results in much better vray materials in Clara.io.
This allows you to do things like embedded rendering: embed a live, vray cloud render of your scene on a website just like you would do with a youtube movie. Check that out here
