Abstract: In one embodiment, a method includes: facilitating an online conference session between a plurality of client devices connected to a meeting server; storing information related to one or more backup client devices, the one or more backup client devices corresponding to client devices that accepted to share their computing resources, and the information comprising, for each of the one or more backup client devices a network address and an amount of available computing resources; receiving, from a client device connected to the meeting server, a request to identify a backup client device operative to process data in place of the client device; and, in response to the request, using the stored information to identify at least one backup client device from the one or more backup client devices, the at least one backup client device having sufficient computing resources available to process the data.

Abstract: A system comprises an interface and a processor communicatively coupled to the interface. The interface is configure to receive a first request from a first device to initiate an online meeting, the first request comprising first location information associated with the first device. The interface is further configured to receive a second request from a second device to initiate an online meeting, the second request comprising second location information associated with the second device. The processor is configured to determine whether to initiate an online meeting comprising the first device and the second device based on the first location information, the second location information, first time information associated with the first request, and second time information associated with the second request.
