I am currently running 3 machines - 1 "main" that I use as my primary and then two secondary systems which are on a Vetra for key broadcasting but then on the two slaves I run copies of Keyclone and 2 clients each. I'm hoping to get another two boxes up and running shortly though so at that point I will be switched over to full hardware

When I am not playing i have a whole array of web-site testing machines setup for browser debugging goodness for the day job
