Patent ID: 7587037

Claim:
A method of conducting a conference, comprising: initializing the conference amongst a host communications device, an intermediate host communications device, and a remote, mobile participant communications device; prior to the conference, communicating a library of digital objects from the host communications device to the intermediate host communications device; during the conference, communicating a synchronization command from the host communications device to the intermediate host communications device that instructs the intermediate host communications device to retrieve an object from memory during the conference; communicating the object from the intermediate host communications device to the mobile participant communications device during the conference; forcing the host communications device to await receipt of a synchronization acknowledgement from the mobile participant communications device before advancing to another object in the library of digital objects, the synchronization acknowledgement thus confirming that the object was successfully presented on the mobile participant communications device; analyzing a communications path between the host communications device and the mobile participant communications device to identify at least one available memory device; determining transmission rates between the host communications device, the available memory device, and the mobile participant communications device; and using the transmission rates to select the memory device from the at least one available memory device.
