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.

Abstract: A system is disclosed that provides functionality for two users to establish multi-modal communication services including voice, messaging, and instance messaging on mobile devices using one or more online community identities. Based on the online identity and profile of a first user of on an online community, a second user may initiate a communications session request to the first user. A service bridging server may incorporate the profile and other information such as presence status of the second user into the session request message and then send the session request to the mobile client of the first user. The first user can act on the session request with a range of disposition options and multiple modes of communication types on the first user mobile device based on the online community identity of the first user and the second user.
