Isn't a Dutch auction where the auctioner(s) start by designating a set price for the beginning of the bidding, and the bidders proceed by bidding a lower price, until no-one is willing to bid LOWER? This is called a Dutch auction because it is employed at the flower markets in Holland (the Netherlands), and is related to the fact that flowers are a perishable commodity. In theory, this procedure would not screw the bidders, so I question your cynical 'sharks' comment.
