I wish they'd take a small number of tickets (10? 100?) and auction them off, with the surplus over retail price going to charity.<p>In general I think all sold out/exclusive events should do this kind of thing; it raises hype, makes the people who get a ticket for normal price feel like they got a deal, and helps the charity. Anyone willing to spend e.g. $10k of their own or a company's money to attend is likely to have some value at the event as well (investor? lawyer?).<p>You don't want to do this for all the tickets, or even a large number of tickets, because having all 5k people be from Fortune 500 companies willing to spend $5k/ticket makes it a lot less interesting than an event with mostly independent developers, but 100 out of 5000 isn't going to change things much, either.
