1. A method of communicating documents in a communication system that includes a plurality of computing devices, the method comprising:

  • determining in a processor of a first computing device whether the first computing device is associated with a first collaboration group;

    determining in the processor whether a second computing device is associated with the first collaboration group;

    establishing a peer-to-peer communication link between the first computing device and the second computing device in response to determining that the first and second computing devices are associated with the first collaboration group;

    exchanging a hints list for an object list that identifies documents stored in a second collaboration memory of the second computing device that are possibly not stored in a first collaboration memory of the first computing device and which identifies a state of the second collaboration memory at various randomly chosen points in an ordered list of objects;

    comparing the object list with the objects present in the first collaboration memory to determine that a document is stored in the second collaboration memory and not stored in the first collaboration memory;

    sending a document request message to the second computing device to request the document;

    receiving the requested document from the second computing device in response to sending the document request message; and

    storing the received document in the first collaboration memory.
