This was 13 years ago so my memory is fuzzy... if I recall correctly, spoofed ARP replies were unicasted to every possible address on the network. It switched from machine to machine slowly, which is fine because they all served the same content.

There were several subnets at the school, each with its own gateway. I remember having to set up live CDs in several computer labs to cover each of the subnets.
