WoW's botters took this one step further, disassembling the game to the point where they made WoW "clients" which could bot/gold farm at <15MB of memory - meaning you could have a hundred accounts botting on one PC.
Ah yep, it was the Defcon video I saw which mentioned it, never saw the C# code. Badass.
Trying to find it, it was a news article written as an interview with one of the original WoW Glider creators and his friend who also wrote bots.. Having trouble finding it..
