A method (300) and apparatus (200) for accessing context information is disclosed. The method may include providing (320) a virtual data source registry (140) corresponding to a local rendezvous point (130) local to a device (110) and a remote rendezvous point (150) remote from the device, where the local rendezvous point can correspond to locally available context information available local to the device and the remote rendezvous point can correspond to remotely available context information available remote from the device. The method may also include receiving (330), at the virtual data source registry, join requests from multiple applications, where the join requests can request context information from a context source. The join requests can include a local join request from a device application (161) in the device to the local rendezvous point. The method may include receiving (340) context information at the virtual data source registry from the context source, returning (350) locally available context information from the local rendezvous point to the device application in response to receiving the local join request, and multicasting (360) remotely available context information from the remote rendezvous point to the multiple applications in response to receiving the join requests.
