The Glassbox 2.0 Beta test started this September. See also https://www.glassbox.com/glassbox/Demo.html for a live demo of Glassbox troubleshooting in action.
We have posted the first build of the Glassbox 2.0 alpha test. It's currently available from http://www.glassbox.com while we set up cvs and serving files through SourceForge.
Thanks and please give us your feedback,
The Glassbox Team
