ABSTRACT:
A distributed software system provides functionality for users to cluster together various types of computing devices (PCs, mobile phones, PDAs, set top boxes, IP appliances, etc.) and associated service resources (landline telephone, mobile telephone, long distance service, VoIP, instant messaging, etc.) to form a service cluster, and to effectively bind the service cluster to a common user identity. The software system enables each service resource that is natively available to a device in the cluster to be accessed and used by the other devices in the cluster. For example, in one embodiment, a call placed to any device in the cluster can be routed to and answered on any other device in the cluster, transparently to the caller. A cluster owner can also grant permissions to other users to use particular service resources available to the cluster. Routing of calls is handled efficiently using a distributed hash table system.
