Password Security and Caffeine Addiction

I note a completely unscientific study (by Verisign) - but it's probably indicative - that indicates that 2 of every 3 San Francisco pedestrians were prepared to provide their passwords in exchange for a voucher for a Starbucks coffee. Which is a remarkably similar result to that found in a UK poll. I wonder whether you'd get the same results by offering a Caramello Koala here in Australia?
