TestDrive is a project that makes it very easy to download and run the latest daily Ubuntu development snapshot in a virtual machine. Actually, it can be configured to download and run any URL-access ISO in a virtual machine. But the primary goal is to provide a very simple method for allowing non-technical Ubuntu users to test and provide feedback on the current Ubuntu release under development.
