Who is Hans Van Eeghen?

For those of you who are following what may be the next Lost ARG.
"Octagon Global Recruiting" finally replied to the emails that we all sent after the commercial aired during the Season 4 Finale of Lost

So far a name has been found that was carbon copied on the replies
The name is Hans Van Eeghen.

Who is Hans Van Eeghen?
I found a few interesting tid bits when I googled his name. Could he be connected or related to the De Groots like the search results revealed?
Also, I sent him an email and this is the auto reply that I received.

Thank you for your email. I am currently on assignment in the field. I will contact you as soon as I am back in the office.
Sincerely,
Hans
