Well, not really...but I ran across this article where Google's packaging a customized "gOS" distribution that is described as a "rather nice slim desktop Linux distribution that would be perfect for Internet cafes and other public places."

We've been using VL for exactly that for years!
Vector plus XFCE's kiosk mode is perfect for the job.
Here's a typical installation. Note that in addition to our own grey all-in-one machines, we usually provide a couple connections for users to hook in their own laptops. There are more of the all-in-ones not seen in this picture. They're around the corner at far end of the area and run a specialized 'registration user' screen that the convention uses for the front end to the registration system.
Here's some of our own screenshots:
1. Guest user screen (the camera/screeshot icon not normally included on panel):
2. Guest user menu open, a game, pidgin, and XFCE media player:
3. Guest user menu with additional expansion, RipperX, Fox Calc, and a links text browser:
Of course there's also full Firefox, Opera, Seamoney, and Dillo, so using Google's web-apps is a breeze.
Maybe we need to pound on Google to use Vector Linux!
