Abstract

Systems and methods relating to a Media Collection Aggregation System (MCAS) are provided. In one embodiment, a number of nodes are connected over a Local Area Network (LAN) to provide an ad-hoc MCAS network. At least some of the nodes in the MCAS network share locally stored media collections, or select subsets thereof, with the other nodes in the MCAS network. Each node in the MCAS network selects and aggregates one or more of the shared media collections to provide an aggregate media collection for that node. One of the nodes in the MCAS network is a proxy node that provides a proxy service that enables remote participation in the MCAS network. In one embodiment, the proxy node enables one or more remote nodes to passively and/or actively participate in the MCAS network.
