I understand the intention is to warn people. But IMO, there are plenty ways of warning or educating them, e.g. blogs, tweets etc. There's no need to 'prove' it just to make awareness.

I did tell my friends and family that a tool (Firesheep) has been released and what is the impact in layman language, and inform them to be careful when browsing through open wifi networks.
