Abstract: Co-authoring of a digital content file using content contributed by peer devices in a peer-to-peer communications network is described. A local copy of the digital content file is stored in each of plural peer communications devices disposed in a multi-node communications network. The contents of the local copies of the digital content file stored in at least two peer communications devices are compared and in an event the local copies of the digital content file stored in a peer communications device is missing content that is contained in the other compared peer communications devices, the missing content is merged into the local copy of the digital content file stored in the peer communications device.

Abstract: Peer-to-peer sharing of information is described. A requester peer device obtains portions of a desired digital content from a select number of provider peer devices. The provider peer devices are selected using statistical information that considers historical data access between the requester communication peer device and the provider communication peer devices. The requester peer device also obtains an amount of error correcting data associated with the requested portions of the digital content from the server. The amount of error correcting data is determined using the statistical information. The requester peer device reconstructs the desired digital content using a combination of the digital content portions obtained from the selected provider peers and the error correcting data obtained from the server.
