The invention provides sampling, escrowing, and other tools and techniques for facilitating transactions that involve digital goods. Transactions may be of the goods-for-payment type, or they may be barter transactions that exchange goods for goods. Digital goods may be escrowed with an automatic broker. The broker may also create and distribute samples of the goods, which are created by techniques such as distorting or burdening part or all of a copy of the goods. In some cases the broker may accept and act on approval or disapproval notices from the parties to a transaction, to cancel or complete a transaction. In other cases, the broker's participation is limited to providing and/or authenticating samples. |
