Val, I'd be interested to know your reasoning behind not naming and shaming your groper at LSF2007. It might well affect how interested I am in inviting him to future conferences or working with him in the future.
It does amaze me how badly some men misinterpret flirting. I would say that I've flirted with at least three of your interviewees at conferences ... without once being under the impression that I was being invited to do more than talk.
I'd like to thank you for bringing this up. I think we all feel that women are under-represented at Linux conferences, and would like to do more to encourage them to attend. Often, we have no idea how to do that, and this is a concrete thing we can do.
