Software executes on the central computer for receiving a request for a specific resource from the client computer. The central computer matches the request for a specific resource to the list of available resources. The central computer provides to the client computer a list of available resources that matches the request for a specific resource. The central computer then receives a buy request from a consumer of the specific resource and sends the request to a supplier of the specific resource.

Abstract: Targeted advertisement delivery to a captive audience, with the content limited to a select group of advertisements, and in a way that advertisers can control where, and to whom the advertisements are shown.

Usage data can be reported back to a server for analysis and distribution to advertisers. Advertisements can be selectively targeted based on demographic, usage, or other information.
