Setting up a mirror for the linux show is quite easy

• Set up icecast according to directions at www.icecast.org
• Add a line "alias linuxlive http://stream.thelinuxshow.com:8000/linuxlive" to your icecast.conf file, or enter the above line as a command at the icecast console. Note that if done on the console it won't save the setting.
• Send email to Kevin with the url for your server and I'll add it to our access list and add a link on our front page

easy enough... if you have any questions you can email me.
