Abstract: A system for establishing anonymous communications includes a plurality of party terminals, a plurality of requester terminals, and a central controller. The system receives and stores party data about respective parties. In some embodiments, a party may be a homeowner. Upon receiving criteria for parties of interest from a requester terminal and authorization from respective parties, the central controller releases to the requester party associated with the parties. The system also establishes communications channels between parties and the requestor, while maintaining their anonymity.

Abstract: One or more proxy bidders is associated with a rule which determines a time to place a bid. The proxy bidder places a bid at the determined time, instead of immediately after the bidder's prior bid is exceeded. Such rules may be selected for all proxy bidders to encourage a desired auction behavior. By controlling the placement of bids based on rules associated with the desired auction behavior, bids may be placed in a manner that seems natural and competitive to bidders in the auction when, in fact, they are placed in accordance with the selected rules. The desired auction behavior may be selected statically for an auction or dynamically during the auction. Historical auction data maybe analyzed to characterize the behavior of an auction, such as the average period of time between bids and the average increment between bids. Rules may be generated to correspond to a behavior so as to provide the same average time and increment between bids.

Abstract: Systems and methods are provided to facilitate a transaction between a seller and a buyer. According to one embodiment, seller offer information is received at a controller. The seller offer information is associated with an item, such as a secondary market item, being offered for sale by a seller. Buyer offer information, associated with a buyer offering to make a purchase, is also received. An evaluation rule is determined, and the seller offer information and the buyer offer information are matched based on the evaluation rule. It is then arranged for the seller to sell the item to the buyer. According to another embodiment, an appropriate item price is determined based on the seller offer information. Information associated with the appropriate item price is transmitted to the seller, and an actual item price is determined. According to another embodiment, a subsidy is determined, the subsidy being associated with a benefit from a subsidy provider to be applied to the transaction.
