I think DAO is a complicated abstraction layer over blockchain protocol, meaning that when you get hacked you don't know how much money you actually lost.
That sounds about right to me. Any insight on how it/they managed to get 100 million in funding? What do all the people sending money think "DAO" is or does?
It's done by taking the amount of Ether it has already raised * the current price of Ether. See it transparently on the Ethereum blockchain: http://etherscan.io/token/TheDAO
