Hi all. To formally introduce myself, my name is...well...look to the left

I am a member of, founder of, and GM for BYOV. Among other things, we run events at Gen Con. I myself run some of our LARPs. I doubt that people on the TD forums are going to be as leary about LARPs on average as other gamers might, but suffice it to say that our 'live action' games are essentially the ROLE playing without the ROLL playing. If you like playing in character, you like plotting and intrigue and such, then there's a good chance you'll like our LARPs (our tabletops tend to be ROLE-play heavy too).
Anyway, on to my question. I've got an idea for a LARP for next year's Gen Con. I think it's a pretty great idea, and had I had it 3 months ago, I'd be running the game at THIS Gen Con. But, alas, it will have to wait.
The idea is this LARP: A Holiday at Hogwarts.
A role-playing stressed game of intrigue and machinations, set in the world of Harry Potter. My question is: how many people would be interested in this game? I don't plan on including 'adult' themes, but simply for quality's sake, I'd like to draw mostly adults to this game. I'm not sure I could take 12 and 13 year olds were they the majority of the players.
NOTE: This game would be set before the timeline of the books/movies, and would NOT include Harry Potter and his friends as characters. The plots would involve an entirely different set of students, namely the PCs.
So how many other adults are there who dig the Potter books, and how many of you would hypothetically enjoy a game like this? No committments necessary or asked for at this time
Thanks. Please poke the poll above, and leave a note below.
