We will be adding to our documentation soon. We have at this point tweaked some setup information to suit our Ubuntu server, from blank to full Wonderland installation. We will be posting that, and some new pieces which reflect getting slideshows set up to run inside the world, and other small enhancements. Yay!
Someone asked me "why Ubuntu" for our server. The truth is that we selected four platforms: Windows (XP/Vista), Ubuntu (as our Linux of choice), Mac OSX, and Solaris. We have material running on Ubuntu and Solaris now.
