I was thinking that the message would appear to have been sent to the chat room as soon as I hit enter, but not actually be sent to the IRC server until later. If the hack is a matter of seeing the question as though it were someone else's question, then that would work. If the hack requires that I genuinely believe that other people in the room have received the question, it wouldn't work as well... but might still work somewhat, if the delay behavior were unobtrusive enough that I partially forgot about it.
