Here is an insane idea.

Seeing as Hawaii has it's own timezone....and assuming people's computers are set to such... Using javascript it should be possible to detect the time and see if it is within 10 minutes of the time in Hawaii or maybe it is possible to determine the timezone from the user's clock directly?

Once/If you have that info you could aJax it back to the server, set a cookie or session variable or something.

I am running on low sleep though so I am not sure how feasible this is
