I'm wary of heading too far down this line because I've certainly done things (hosted X-rated parties, etc.) at conferences in the past, which I certainly wouldn't do as official conference events under a company name with random people, but which seem fine in a social setting. And gotten drunk on stage, etc.

But at a "hacker" thing (DC7-13, etc.), not at a developer conference or professional event. There probably is some evolving standard of conduct now that things which were formerly mostly underground are now essentially big business.
