ISP in a box

Nerd Vitals have 3 articles currently, and more i think on how to turn your
mac mini into an ISP in a box. In part 1 they show you how to set
up Apache, etc. Part 2
shows you how to setup mail servers, etc. final one on the site at the
moment is how to setup MySQL.
Very interesting read. check it out. if its any consilation, i have an ISP in,
well, 3 machines… do i win?
