The remaining stakes will be distributed via an auction. UP explained somwhere hot it'll will work I can't find the post right now but it'll be a simple auction where the highest bidder wins.

I agree. Our initial thought is to offer the first auction on the Alpha release to avoid scam accusation and we will take some times to build the brand up to that point. The likely method of auction is http://en.wikipedia.org/wiki/Multiunit_auction. We will write a more detail guidelines at least one week before the auction but that's something everyone can study first if they are interested in the auction. Uniform auction have been used for U.S Treasury auctions. You can read about the theories and empirical studies of this type of auction here http://www.treasury.gov/resource-center/fin-mkts/Documents/final.pdf  and here http://www.treasury.gov/resource-center/fin-mkts/Documents/upas2.pdf
